Okay, I’ll admit that Legos are a cliche in math problems for kids but to my credit, the student I was talking to suggested that Legos are something we buy in different sized packages.

Here is the problem:

Sally wanted to buy 473 legos. At the store they are sold in packages of 100, 20, 5, and 1. Show all the ways you can find that she can buy the exact number of legos.

Use pictures, numbers, and words to prove your answer.
