### How Close to 100?

This has been a very popular game in our math group, and I think it has a lot going for it. For one thing, it relates very well to our overarching theme of "number sense". For another, it is a fun way to visualize and practice multiplication. I love games where partners or team cooperate to achieve a common goal, rather than complete against each other. Lastly, it is a game that is simple to learn and takes few materials - you could certainly play it at home (and I encourage you to do so).

With a partner, you need a pair of dice and a hundred grid. Take turns rolling the dice and write down the two numbers in a multiplication sentence. Then color in the array on the number grid. (5 x 4 = 20, color 5 squares across and 4 squares down, 20 squares altogether, for example.)

If you can no longer fit your array in the grid, you lose that turn. After 10 rolls, figure out how many squares you filled in, and that is your score.

Although this game is recommended for grades 3 - 8, I find my group plays it very well.
