- they’re fun.
- skill practice with engagement that worksheets can’t match.
- sometimes the game can support the underlying concept development.
- sometimes they can be the context to help conceptual understanding.
- provide an opportunity for problem solving in the context of game playing strategy.

I often launch a game by playing me vs. the entire class. It tends to communicate more of the rules than just explaining them. I’ll often have students play in two person teams to start, as their discussion helps work out understanding of the game and the mathematics. After the lesson, I’ll try to engage students in a conversation about what they noticed, what their strategy was, and if they would change anything about the game.

The games for today: you will rotate through the tables, spending a few minutes trying out the game at each stop. This may not be enough to finish a game, but will hopefully give you an opportunity to get a good taste.

**Game - Presenter - Content**

- Consecutive Capture - Emily Trybus - Integer representation on the numberline
- Tug of War - Anne Harkema - Integer small number addition, especially positive + negative.
- Close to Zero - Jill Beauchamp - Two digit integer addition, especially positive + negative
- Zero Rummy - Cassie Becker - Integer addition with more than two summands, especially zero pairs and sums.
- Gridfight - Kirsten Clemans - Integer multiplication
- Honeycomb - Nick Smith (game coauthor) - Integer multiplication and addition
- +/−24 - Emily Scothorn - Integer operations mixed plus order of operations

At the end we’ll try to come back together to discuss which games you liked the best for your classroom and why.

The most interesting games to me are Gridfight and Honeycomb. My preservice middle school math teachers helped with the playtesting of these games, and gave a lot of valuable feedback. Consecutive Capture is a nice variation of Fraction Catch... which I was about to link to, but I guess I haven't written about yet... and the preservice teachers were fond of it. Most of the games had someone who really liked them, with the possible exception of Treasure Hunt, which is meant to be a quick and easy introduction game, and indeed the preservice teachers found it simple.

The idea behind Gridfight came from wanting to get at the area model for multiplication. I like the way it kind of presages Algebra Tiles. The goal of filling in rows enables you to win even when the other person gets more areas to fill in. The strategy of it appealed to students, and it had a lot of replay value.

Nick Smith, one of the preservice teachers and the presenter for the game, came up with a lot of the idea for Honeycomb. He was sold on the hexagonal grid, and had the idea of flipping and replicating stacks of two color chips to get the feel for multiplication by a negative. We wound up making it a pen and paper game as it was clumsy with the chips. It's got a large luck component with the dice, but enough strategy to keep people engaged. This is a game I'd be interested in seeing implemented on the computer.

I hope you enjoy the games, and would love to hear what you think if you get a chance to try them.
