Love it, but.... – Subtracting Sardines HD Review

My students use this and other apps by Operation during math time. They absolutely love them! I have a student who is struggling with subtraction. This app allows her the opportunity to visually see the little sardines disappear as she is subtracting. The game is engaging. However, I just wish there was a way to block out negative numbers. If there is a way, I haven't figured it out. :)
