There are blocks of 4 colors. Pick 5 blocks at random and hide them. Use the following code to calculate the product of the blocks. Inform your partner the product and let her guess what blocks you have: Red = 2; Blue = 3; Green = 5; and Yellow = 7 For example 2 blue blocks, 2 greens and 1 yellow gives you 3*3*5*5*7 or 1,575. Which blocks does your partner have if the product she tells you she got is 630? How about 500? Or 378?
