Students play this game in groups. They choose 6 dominoes, and count the dots. Then, they find the mean, median, mode and range of their numbers. The students fill out this score sheet to find the "winner" at the end of the game. Great, fun way to review these concepts. Use Mexican Train dominoes for larger numbers, and regular dominoes for smaller numbers.
I've taught a variety of subjects and grades, including eight years at 4/5, two years teaching middle school Language Arts, and this is my 4th year teaching 7th grade Math and Pre-algebra.
