Begin by thoroughly going over the details of the project. Teach the students how to curl cardboard (cereal boxes) by wrapping a strip around their finger tightly. This technique will help students with "curvy" numbers. Teach the students how to create multiple L-Braces with cardboard strips and tape by lining up a 4 cardboard strips vertically, connecting them each with a strip of tape, and wrapping them to create a rectangular prism. This technique will help students with "straight" numbers.
