*Materials*: deck of angle vocabulary cards, blank paper, ruler, pens, protractor.

*Set up*: (make if necessary and) shuffle angle vocabulary cards.

*Draw phase*: teams take turns

- add a point, and
- connect to one, two or three other points from your new point.
- each team adds right angle mark or congruent length if that's their intent
- both teams make 5 points.

*Play phase*: on your team's turn

- roll a die (that's this turn's points)
- flip a card. Claim an angle or a set of angles that fit the condition. You can only claim unused angles.
- score that many points for each angle you claimed that fits the condition.
- check: if you can't find one or find one mistakenly, the other team can catch you for 2 points per angle.
- game is to 20 points, run out of cards, or all angles are claimed.

**Design reflection**:

Could use a context, but the only thing that comes to mind is shooting metaphors. Maybe bird watching? You know how the kids love bird watching!

Foxtrot, of course, has angle games covered. They even get triggy with it. |

*Possible starting card set*:

- an acute angle
- a right angle
- an obtuse angle
- a pair of congruent angles
- a set of congruent angles that are not right angles
- a pair of complementary angles
- a pair of adjacent angles
- a pair of cute adjacent angles
- a pair of acute obtuse angles
- a pair of vertical angles
- a set of angles that add to 180 degrees
- a set of angles that
- a pair of corresponding angles
- a set of interior angles
- a pair of congruent exterior angles
- a pair of angles that add to 180 degrees
- a straight angle

*Warning*: only roughing out playtesting so far.

What do you think?

I wonder if the intro playing field can be more procedural in its creation. Like, a set of transparent cards (like in Swish, in transparencies) that you overlap following rules in the cards thenselves, to create dynamic new boards that still include many of the elements you are long for (which player-created boards may not).

ReplyDeleteCool idea. Would love to try it out with my 7th graders!

ReplyDeleteI like what I'm reading. I was thinking about having the "boards" being pre-made as an introduction, but you already thought that too. I was also thinking about area control. What if there was some type of bonus for claiming all the angles of a triangle (or something to that effect). Perhaps instead of flipping over 1 card, they flip 2 and pick 1 to use???? Just throwing out some thoughts I had, not even sure they would work.

ReplyDeleteI really like all the math they would be elbow-deep in here. Great stuff!
