Stamp Shortage

Stamp Shortage is another great math activity which was provided by the Georgia DOE a few years ago. The problem says:

The local grocery store has run out of 47 cent stamps. The only stamps left are 2 cent, 3 cent, and 4 cent. How many different combinations of stamps can be used to make 47 cents?

 My students were given 47 uni-fix cubes and told to make groups of 2, 3, or 4 to represent the stamps. They then had to write matching multiplication sentences and add their products to make sure they did not go over the 47 cent stamp cost.

I only required them to find one way to solve, but gave extra credit for every way beyond the first way if it was accurate. I had one student come up with 10 different, accurate ways to solve! AWESOME, I know!
