This is a fun project that helps kids master BEDMAS. I've used this project for a few years and my students have always loved it (most of them anyways). It often becomes a competition between friends to see who can find the most expressions. Even the students with difficulties can do this project. It is easy to make adjustements for them (less expressions, not having to use all the numbers in each expressions, etc.)
