Math Performances

 I'm teaching a summer algebra course for incoming students. It's our intermediate algebra course stretched to two semesters, my first time teaching it. Part of it uses or parallels Stanford's How to Learn Math course. We work on number flexibility, patterns (a lot of visual patterns), graphing, proportional thinking, and linear functions and systems. It's part of our Oliver Wilson Scholars program, which works on community building, transition to college, and college success strategies, plus a start on math and english coursework. Each course has an assigned tutor who attends class and works with the learners directly for tutoring sessions. Lyndsey is our tutor and they are doing a smashing job.

In general, I love the graphing stories/lessons (web archive) from Dan Meyer. Of late, I've been doing them via Adam Poetzel's Desmos activity, but did find a current site with all the videos. For this class, I wanted something more experiential. Back in the days of TI calculators we had the motion detectors and I loved those walk the graph lessons. (How can we not have a motion detector app for smart phones?) Lyndsey thought of having groups perform for each other. I came up with four scenarios for them to do, and one that I could demonstrate. Distance of the head above the ground, distance from the edge of the whiteboard, distance between two people, and distance between a person and a ball.

Warm up was to try to guess the joke from this comic. They hadn't heard any of the expressions, but were able to use the 2nd and third graphs to guess at them.

I kept the 15 second time frame. I wanted movement that would be traceable at a classroom scale. I asked them to make it repeatable, and had them perform it twice. Once so people could see what was happening, and once for data. Instead of a hard 15 seconds, we had someone in the course count out loud. The most complicated performance was a minute with slow counting, but it didn't seem to bother anyone.

Here's the handout, with a couple questions revised after doing it. The screen for demonstration was pretty viewable. I wrote a script that I followed.

3 seconds pull down slow

Let go 2 seconds

Pull down fast 1 sec

Stay 3 sec

Put up half way 1 sec

Stay 1 sec

Slow up 4 sec


I got a little messed up with the counting, instead of 1 to 15! And there are some surprises trying to do anything in real life, so the practice was different from the data round.

We compared data, graphed the result, and compared the graph to what happened. One notice was that the graph was kind of the opposite of the motion, it went up when the screen came down. This is definitely a challenge with qualitative graphs, wanting the graph to somehow be a picture of what's happening. If you have a chance to have learners graph what happens to height above the ground when climbing and coming down a slide, you'll see what I mean.

Though I was nervous, new lesson, new course, it worked better than I could have imagined or had any right to have it go. They came up with creative movements, and it seemed to really help with an intuitive meaning to the graph because of the connection to the kinesthetic.

Here's the folder with all the videos

The sequencing worked out pretty well. I think the head above the ground was the easiest to understand, and the graph parallels the motion in a natural way. Distance from the edge of the whiteboard was easy to understand. Distance between people was fascinating, and I'd love to do that in a college algebra or calculus class to graph both positions and then the difference. The basketball was really surprising! I expected a much slower and varied trasfer, but the rapid passing gave them a lot to notice and made data collection a challenge.

They selected one of their graphs to turn in, answering an additional question about how does the graph show the action. Maybe I need to come up with a better way to ask that, but there were some good responses. A lot of understanding about data to graph, and some good understanding of the graph properties. Some confusion about minimum and maximum, which makes sense to me since there were two sets of data, really, the x and the y

The follow up the next day was Four Corners, a game for practicing coordinate graphing. Not a hit, but good practice. A couple pairs got really into it.

I'll definitely try this activity again, so if you have ideas to improve it or just to try... hit me!

World Tessellation Day '26

 Some of my favorite tessellations from this year!

To me the 2 greatest current tilers I know are Ghee Beom Kim and Miki Imura, who both share a lot on Facebook.

Kim: often works with simple shapes, great fractal connections.




Imura:


Although Regolo is still killing it.

Most of Acid Lich's work is more abstract, but this was fun with the Einstein tile.



Hana Murray may be closing out her daily pattern block work, but she has made hundreds!


I've enjoyed a lot of David Houlton's work this year (in the FB Tiling and Tessellation Group). So clean!



We'll close out this section with the ultimate in tiling personal protection from Dr. T:



Not the same as these geniuses, but a few of my favorites from what I've made this year. All of these are interactive - links go to GeoGebra.

Two rhombus tilings.


Based on a tiling seen in Renesse, France.

From a two tile tessellation.


From last night!


Looking for more? Check out what I share on Bluesky or last year's post. Or make your own: Steve Mayne made an amazing tiling app this year.


We'll close with this sweet tessellation from one of Xavier's learners. Not only is the art amazing, but look at the great rotation action!

AL, Comical

 

AL, Logical, available on Kickstarter until March 5th!

Perhaps the question that have come up the most in discussing AL, Logical with people:

Why a comic book?

Time passes between panels, and it's especially good when we are seeing problem-solving. Something happens. She's THINKING. 

The reader's perspective can be quite different than in prose. Xavier (coauthor, pencils, inks, colors and letters!) is especially strong on showing action instead of telling about it. When the house is moving, we don't see the house changing, we see the elder god seeing the house changing (we see it in its eye). It's humanizing.  Comic books help you to take the perspective of the people in the story. We see AL the way the mathematician sees her, and vice versa. 

And then there are all the joyful little visual tricks he does, like "hey there" backwards in Chapter 4. Fun, but also serves the story. It also offers the reader a chance to notice. Also in Chapter 4 there are a lot of clocks. What's happening with them? 


A big part of our impetus for writing the book is that I see math as being all about problem solving, and he sees art as being all about problem solving. And he does a lot of problem solving throughout the book, which gives readers two ways into AL's problem solving experience.

In a sense, the comic book format literally allows the reader to see math how we see it. 

This might be just because we are a comic book loving family (well, 3/4 of us and one patient parent), but comics are a story form that invites rereading. Even a 70ish page comic like this one is about like three issues of a comic book. Readers have taken from a half an hour to an hour to read it, almost inviting you to pick it back up, look at specific pages, see if the beginning makes sense with the end... go where your attention takes you. Partly because of the story, and mostly because of Xavier's art, the comic really offers a lot of chances to make connections as a reader, and to notice AL making connections in her thinking and experiences.

There are some other math comic books (see the list at the end of the AL, Logical page on the blog), but this one is pretty distinct from those. As fond as I am of them! In our comic, we really worked to make it about the narrative, not a math lesson in disguise. While still having fun, real mathematics.

Please take a look, and help us spread the word.

PS> My previous blog post about the book goes into some of the relevant frameworks behind the math content and the math processes we get to see in the story.

AL, Logical

 The mathy graphic novel I wrote with my high school art teacher son Xavier is up on Kickstarter!


The Kickstarter has a lot of information about the story, so I'll geek out here a bit more.

We started with the protagonist: a middle school student who knew she wasn't a math person. The haunted house idea came along pretty early. And a pretty cosmic haunted house with some Cthulu near relatives peeking in.


One of the frameworks we built the story around are the Van Hiele levels of geometric reasoning. This let AL develop and tackle more complex problems as the story progresses.


Though AL does more than geometry as she's tackling problems from all different kinds of math.

A lot of math comics are directly trying to teach some specific content. This comic is about trying to show the experience of doing math. The framework that helped the most for this is from Tracy Johnston Zager's Becoming the Math Teacher You Wish You'd Had. These chapters...

3: Mathematicians Take Risks

4: Mathematicians Make Mistakes

5: Mathematicians are Precise

6: Mathematicians Rise To A Challenge

7: Mathematicians Ask Questions

8: Mathematicians Connect Ideas

9: Mathematicians Use Intuition

10: Mathematicians Reason

11: Mathematicians Prove

12: Mathematicians Work Together and Alone

... really give you a great feel for what doing math is.

All this might make it sound dry, but the focus was on the story. Very inspired by stories like The Phantom Tollbooth, and our love for comic books, we were glad to see that the beta readers found it fun.


More about the story and other mathy comics in the AL, Logical tab, and of course at the Kickstarter!

Who WIns?

 I'm teaching our Statistics and Probability for K-8 Teachers for the first time. Had excellent support and suggestions from Jenna Laib, colleagues Jon Hasenbank, David Coffey and Hope Gerson, and from Stephanie Casey and ESTEEM folks.

Working out bit by bit what we're going to do. Luckily I get to teach it again next year...

We just finished our first week, and I loved how the Day 2 lesson worked out, so I wanted to share it and think about it a bit. I miss the reflection of blog writing about my teaching!

On Day 1 we had started exploring measures of typical. We got out the unifix cubes, and did a bit on how could we make the distribution more fair. It took several rounds of give aways, but we got there. Some tubs of 252 and some with 251. Then each person built a stack as long as their first name. We organized from shortest to longest and thought about how to answer "How long is a 323 student's first name?" We had initial estimates, then talk went to median and mean. We retooled and did full legal names. Much bigger range, but a surprisingly dominant mode. So there was another consideration. Our emphasis was not the number you said to answer the question, but why you would say so.

Each day one of the teachers leads a Slow Reveal Graph, and Day 2 Tessa started us out on Disney Princess Baby Names, so energy was pretty high. If they had to name kids with Disney princess names they'd go with Belle and Aurora. Yvette's great question was what can you say about this without calculating?


Good discussion. I added in that since all of them had 7 elements, we could just look for a total instead of dividing. Some good call backs to Day 1's discussion of mean and balancing or distributing.

Then the main activity. They used NRICH's great millisecond timer tool and each collected 5 points of data for trying to hit 10 seconds exactly. They each found their median and mean, and thought about what would make a better measurement of who was best at estimating 10 seconds. Uniformly, each table decided on the mean. I raised up the idea of how some sporting events use your best score. They decided that they wanted to include outliers, that consistency matters.

The NRICH page that got me started on this idea had a set of data for discussion, which they credited to the great Don Steward, from his awesome Median blog.

Anna

Ben

Charlie

31

36

37

26

19

32

32

39

24

27

36

32

29

20

30

Typically great prompt from Don. They all found Ben had a mean of 30, though they all thought he was the worst of the three. People were divided over whether Anna or Charlie should win. People liked Anna's accuracy, but others were compelled by Charlie's spot on 30 seconds. They had time to propose a new summary statistic to answer the question of who is best.

One table proposed |mean-30|+|median-30|+range, low score wins. Another table proposed just the best score, tie broken by 2nd best time. Voting was mostly in favor of the more complicated statistic. But definitely the Charlie fans wanted best time. 

And then the breakthrough moment! Someone said 'What if we just totaled up how far each guess was from the target?' Absolute deviation! I tried to play calm and cool, and gave them time to think about it.

Revoted, and people went 22/24 for the absolute deviation. My inner teacher was screaming.

They reevaluated their own times using this metric, and decided on a table representative for the class champion. Then, a class championship, three rounds. Very exciting, started close, and then someone ran away with it.

In their summary, lots of great discussion about variation, mean, median and their limitations.

Playful Math Carnival 183

Welcome to the 183rd edition of the Playful Math Carnival. Begun by Denise Gaskins, previously known as Math Teachers at Play. If you'd be interested in hosting, just drop her a line. Previous editions are listed here! The most recent was Sue Van Hattum's Storytelling Carnival.

183 is a semiprime - though not too mysteriously, as 3 is a factor.

183 squares in this quarter circle. (Cf. A001182

New to me was Legendre's Three Square Theorem. Every number can be written as the sum of three squares, unless it is of the form 4^k(8*m+7). (Number theorists are wizards.) 183 = 8*22+7 so it cannot be. Also then, 175 and 191 cannot. Are there any closer integers to 183 which cannot? 

The totient of a counting number is how many natural numbers less than it are relatively prime. The totient of 9 (8, 7, 5, 4, 2, 1) is 6. The totient of 6 (5, 1) is 2. The totient of 2 is 1. Since 9 = 6+2+1, it's the sum of its iterated totients, which makes it a perfect totient number. So is 183! What is its totient sequence? I'll get you started, Ï•(183)=120. 

Projective planes are a fascinating structure that grew out of the study of perspective. One way to generate them is from a finite field. A finite field of order p^n (p a prime) has a projective plane of (p^n)^2+p^n+1 points. The Fano Plane on Z_2 is the most famous example. In our case, 183=13^2+13+1! What's the one before and the one after in this pattern?

183 is also in the sequence n^2-n+1, Hogben's oddly called central polygonal numbers. That means it's on the diagonal of the Ulam spiral. Which side will it be on?


Do you have a favorite 183 fact I've missed?

This edition is dedicated to those regularly producing and sharing new content. 

Regulars

Karen Campe is the definition of regular! Ever month a calendar of problems, and more besides. For example, December 2025 and her Pythagorean Squares activity.

Jim Propp does a monthly deep dive into a different topic each month for his mathematical enchantments column. So carefully crafted and well written. Consider this on Matrix Multiplication. Is it ugly?

Monthly? Pshaw! Pat Bellew has a daily post: on On This Day in Math. But also many other tidbits, like what about monkeys typing Shakespeare? (Of course, some wit pointed out that we already produced a primate who wrote Shakespeare. Shakespeare.)

Denise Gaskins gets close to daily, with her weekly Monday Math Games and Thinking Thursday and other posts besides.

Jenna Laib is a treasure trove. In addition to regular, amazing Slow Reveal Graphs, like this one on butterfly wingspans, she writes deep think pieces like this on culture and identity in math class.

David Petro does a regular feature with lists of resources as well.

Colleen Young does a feature of her own gathering links from all over, but also other posts, like these nifty RISP problems.

Kristin Gray covers a variety of topics, but I particularly enjoyed her list of math stories.

Maths for Humans has a variety of content, but I enjoyed this reflection on learners' problem solving.

Cambridge Mathematics does a monthly Espresso summarizing math ed research, and other features like their new podcast.

The Futility Closet isn't just math, but has amazing tidbits on a frequent basis. Like Lee Sallow's geomagic squares

I'm new to Dr. Austin's Maths, but she adds good problems on a regular basis.

Substack

Dylan Kane weekly shares his deep thoughts on math, teaching and teaching math. Here he pitches gradual increase of difficulty, vs release of responsibility.

Fawn Nguyen is back writing again. Some refreshed old hits, some all new content. Always amazing.  Here she's writing about when students write the questions.

Dan Meyer writes a lot about edtech especially AI, but still does some straight teaching talk, too. Like teaching is harder when the math is easier.

Grading for Growth is an alternative grading blog, featuring two of my colleagues among others. Here's Robert Talbert writing about the Four Pillars of Alternative Grading.

Videos

Christina Tondevold's got a regular Buildring Math Minds video series. I thought this one was a big one on the purpose of math learning, Doing and Thinking.

Meet a Mathematician introduces us to mathematicians and math teachers, like the cool Greg Lakey.

Kyle Pearce & Jon Orr have a Make Math Moments video more than once a week, tackling issues like moving towards efficiency.

Watch everything Howie Hua makes. Here he's arguing that 3x8 and 8x3 are different.



Here and There

Grant Snider is a brilliant cartoonist, getting a bit mathy on occasion. Especially with this bit on infinity.

Dan Scher is the leading person I know on Web Sketchpad. Here he shares a new idea Algebra Mazes.

You never know what Tanya Kovanhova is going to write about, but here's a math magic trick.

Sue Van Hattum is writing a terrific math series, getting at big ideas from an accessible angle. She'd love some beta readers... And she has put together a collection of teaching gems from the books.

I've been enjoying the art from the JMM/Bridges 2026 show.

Crazy cool Möbius band explorer from Ben Sparks.

Those fool Teaching Like Ted Lasso guys are back with a new episode on Joy and Softball

Sophia (FractalKitty) leads #mathober every year. Lots of interesting bits of math, art and coding were shared. 

Puzzles/Games:

  • Karen Campe suggested two. One Up, a kind of number maze.
  • Jigsy is the other. That's had an open tab since I first saw it! A geometric puzzle where you can scale the pieces. So clever. I appreciate the levels of difficulty.
  • Dive also gets a permanent tab. It's like 2048 for factors.
  • A Mathblr user came up with these neat irojirai puzzles on coloring a square.
  • I gathered 13 fraction games from a teacher ed course. 
  • I also tried to make a tangram like puzzle with 30-60-90 triangles. Here's some examples.

A list of 183 cm tall celebrities? I don't know all these people.


And on that note, I'm out! Hope you found something to get you playing with math.

13 Fraction Games

 As a part of Michigan's restructured elementary certification, we got the opportunity to restructure our two math ed courses for elementary into an introduction with geometry and measurement (Statistics has a companion course on data and statistics.), Number and Operations, Fractions and Decimals, and Early Childhood Mathematics. Most students will take all four, depending on grade band certification, and those with a math emphasis have 3 more. (I'm teaching the statistics one next semester for the first time in Winter 2026.) I taught the fractions course for the first time this fall, and thought I'd share the fraction games we used. It's a community-based learning course, so we met at an elementary school and taught kids twice a week, one 4th and one 5th grade lesson. So these are kid tested! Mostly they are shared elsewhere or modifications of games I hope you know already. Games without a creator name are mine or my variation on another game, though most of these are pretty simple so I'm sure they're out there from others!

The course begins thinking about fair share problems in context. 3 brownies to share between 2 friends. How much does each get? And trickier and trickier from there. The pictures learners make from these problems are our first models.

Then we start exploring a more formal linear model of fraction bars for 1/2, 1/4, 1/8 and 1/16. Sometimes I'll have them make their own from construction paper, sometimes cut and decorate from a print out. On card stock if that's a possibility. With these two classic Marilyn Burns games, there's so much to notice. Composition and decomposition, equivalence and more. But they start where I want to start. Fractions are quantities in relation to a whole. Fraction numbers are inherently confusing. A 1 and a 4 and it means something different... division is involved somehow? 

Fraction Cover Up
By Marilyn Burns

Fraction Kit for each player/team.
Die with ½, ¼, ⅛, ⅛, 1/16, 1/16 or a spinner set to the same.

Put the whole down. The goal is to cover up the whole EXACTLY with the pieces you roll.

On your turn: roll or spin. Add that size piece to the whole. If the piece is too large to fit in the space remaining, pass the turn.

First team to cover exactly wins.

Example: You have ½, ⅛, ¼… and you roll ¼. Too big, pass the turn.

Fraction Uncover
By Marilyn Burns

Fraction Kit for each player/team.

Die with ½, ¼, ⅛, ⅛, 1/16, 1/16 or a spinner set to the same.

Cover the whole with two 1/2s. The goal is to uncover the entire whole exactly.

On your turn roll the die. If you have that size piece, remove it. If you don’t have that size, you have an option. You can break up a piece into any pieces which equal it. You can also choose to keep the pieces you’ve got.

Example: You have two 1/2s, and roll a ¼. Bummer! You choose to replace a ½ with ¼, ⅛, and two 1/16. 

Example: You’re down to just a ¼ and 1/16. You roll a ⅛. Bummer! Do you break up the ¼ or keep it?

Extras:

Eighths vs Sixteenths

One team gets the eighths and the other the sixteenths from the fraction kit. The eighths team has a spinner with 1, 2, 3, 1, 2, 3, and the sixteenths has a regular 1-6 die. On their turn, they spin or roll and get that many pieces. Trying to make exactly one. If you need 2/8 and spin ⅜, you pass your turn.

On the replay, switch sides.

Be sure to ask teams how much they have and how much they need. This works on iteration, adding with like denominators, and sums to 1.

Another early fraction game I love that can be repeated later is I Spy a Fraction.

I Spy a Fraction

Stand in a circle so you can see one another.

One person in the group says I see something true about ____ of us, filling in the blank with a fraction. Others, starting to the right of the spy, try to guess what characteristic you’re describing. Once someone has guessed (or there are no more guesses) invite another person to spy a fraction. (I often start with glasses.) To choose a next spy, you can go around the circle in order, or have the person who guesses correctly be the next spy. Play several rounds.

Depending on student experience, you can try giving a reduced fraction. You may have to specify whether you are included or excluded to get a total that can have simplified fractions. Students new to the game or to fractions, keep fractions unreduced.

Fraction More

One game board.
Each team needs 12-16 squares of one color. (Or any markers you can tell apart!)

Before playing the game the first time, it is a great idea to see what some of the fractions look like. Roll the die, and practice making 1/16, 1/8, 1/4 and 1/2. Look for how repeating those amounts divides the board into that many pieces.

Start: both teams roll the fraction die (or spinner marked ½, ¼, ⅛, ⅛, 1/16, 1/16). The SMALLER roll goes first and fills that fraction of the squares.

Then teams take turns rolling the die and adding that fraction of their color to the grid. If there is not enough room, you lose your turn.

When the grid is full, the team with more than half wins.

Look for opportunities to describe the state of the board with fractions. What fraction of the whole board is blue? Is empty? Is red? Is filled? We’re looking for being able to use fraction names for quantities sensibly.

16ths Nim
Draw a 4x4 grid. 
On each team’s turn, they can fill in one, two or three sixteenths. Count as they fill in the total part of the board filled.
The team that fills the board LOSES! Losing team chooses to go first or second in the next game.

Good for naming amounts, and getting to iterate. Kids typically find this pretty engaging. A bit easier than the fraction bar Nim. 

Kids almost immediately started drawing other size grids, which is awesome! Work on naming those fractions.

The Deck
Over the course of the semester, the teachers work on building a deck of fraction cards. At first just number cards and bar model, then adding area and discrete models and more fractions over the course of the semester. (Here's a GeoGebra applet I made to help.)

Concentration (Memory)
A deck of about 20 fraction cards from two halves of an index card. On one half of the card, the symbol for the fraction, like 12, and on the other a fraction bar representation. 
I might make: ½, ⅓, ⅔, ¼, 2/4, ¾, ⅙. 2/6, 3/6, 4/6, ⅚, ⅛, 2/8, ⅜, 4/8, ⅝, 6/8, ⅞ or a subset of those.

Lay out the cards in a grid. On a player’s turn, they flip over 2 cards. If they match, they score them. In memory/concentration at home, you probably take another turn, but I recommend NOT doing that in school games, as it leads to less turns for the kids you want practicing more!

There is some strategy to concentration, in terms of flipping over a new card or known card first. You might talk about why you’re doing what you’re doing as you play. 
It sometimes helps to have the kids make all the pairs before the first game, so they can see the matches.

This game was surprisingly popular with the kids, with them often requesting it up until the end of the semester.

Fraction Go Fish

Use your full deck of cards. At least 8 cards for each player.

Deal each player 4 cards. On your turn, ask ONE player for one fraction. If they have it, they give it to you. If they don’t they tell you to GO FISH, and you draw another card. At the end of your turn, if you have a match, you can play one match. No extra turns!

Play continues until someone goes out, or you run out of cards. If you run out of cards, everyone gets one more chance to ask for a card.

Be clear that you can match two pictures if they show the same fraction.

Equally popular with memory. Some groups focused on a set of numbers and one model for each number so players new if they were asking for a number or a picture.

1s Go Fish

Instead of looking for different representations, players look for fractions that add to one. Eg. ¾ and ¼. They don’t have to be the same representation. As usual, it’s good to practice making pairs before trying in the game. Make sure that all the cards in the deck have a match! Remove any that don’t.

Fraction Path

Make a path with 6 spaces on it, and a clearly marked start and finish. The goal is to fill in your path from smallest to biggest fraction. Once you place a fraction, you cannot move it.

Players take turns drawing a card. If you can, you have to write it in a spot. If you don’t have a spot that works, you lose your turn.

First player to fill their path from smallest to largest wins.

Great after activity: make a number line 0 to 1 with the numbers in your path, placed as accurately as possible.

I am a huge fan of path games. Once learners are comfortable with the quantities and representations, it's great to move on to comparison, and even relative magnitude like the number line post activity. You can adjust the number of spaces, but 6 made for a game quick enough for our instructional time frame.

More or Less

Players each have a hand of 3 cards. On your turn, you call whether more or less wins. Players choose a card and hold it out face down. Everybody shows their card at the same time. If there’s a tie for least or most, just those players play another card from their hand with the same rule. Draw back up to 3 cards. After once through the deck, players with the most cards win.

Nothing wrong with War for number comparison, but this simple modification adds a lot of choice and strategy.

Fraction Dice War

Using the fraction dice from earlier in the semester. Teams roll two dice (or one twice). The team with a higher total gets a point. First team to five points wins. 

Very simple. Encourage pictures to compare, or use the 16 grid and counters to show the fractions. A good early adding with different denominators game because you only have to change one one of the addends.


A Little Bigger

Materials: a deck of fraction cards.

Deal 5 cards to each player or team.
Player to the left of the dealer plays their smallest card. 
Each subsequent player has to play a card greater or equal to that card. For example, if the card is ¼, you could play a picture of ¼ or a ⅓ or ½ or…
If you can’t play a bigger card, draw a card or take the top card off the pile.
When no one can play a bigger card, discard the stack. The last player who played starts the next stack with their smallest fraction.
First person out is the winner! (Or play until there is only one player left.)

Here We Go

Next semester I have a new class working with the same kids, so we'll be needing some new games. I'll still have them make a deck of fraction cards. But we'll need new games for fraction equivalence and more operations practice. 

What are the fraction games you like? Share some back.
