Cootie Catcher Fact Families

Modified from Fold a square of paper into a “cootie catcher.”  I will modify it so that all the numbers on the tool are in the same fact family, the 4th flap on the first layer will be a x/÷ instead of a number. (For example, 6, 5, 10, and x/÷ on the first four flaps, the next layer will have 6x5, 5x6, 30÷5, 30÷6 with different configurations, but so that each flap shares the same answer with it’s pair.
