Diamond Factor

Comments: 

This app effectively gives students practice at filling in diamonds for various quadratic factoring diamond problems. This is definitely an app that needs to be given to students during this unit when they already have knowledge about how to fill in a diamond and its connection to factoring quadratic equations. Once they have this knowledge, this app is great for practice and student feedback. It is better than DiaMath because it allows for more complex equations.
