Wow! – FlowPlus: Add. Subtract. Enter the Flow. Review

Ok I'm actually embarrassed! As a math teacher of 6th graders I thought I mastered addition and subtraction! This app proves...beyond a shadow of doubt that I am a novice! This app is for everyone who is not afraid of challenge. This app will immediately show you that what you thought you knew...you really don't. The reversal challenge was the first game I chose when I opened the app. Wow is all I can say! No educator should be without this app.
