Materials: number mat for each player or pairs, two cow counters or other counters for each player.
1.The first player drops two counters onto the number mat.
2.The player tells their partner the two numbers and then has to tell a subtraction or addition number story. (I would only choose one)
3.The player then illustrates their number story and writes the equation to match. (Students need to understand the greatest number goes first.)
I have also included cow counters if you do not want to use regular counters.
