This is a great activity for partners or math centers. There are two different variations depending on how much your students have learned about operations with integers.
Students will either practice adding positive and negative numbers in one variation of the game or multiplying integers.
This activity will require different colored dice. Preferably red and green. I bought mine off of ebay. You could use blank dice and write on them with red and green markers as well. Teachers can be creative and resourceful so I am sure there are many other alternatives.
