This app is fantastic! I had heard lots of great reviews from friends and colleagues and I can say it worked really well in my classroom. This app targets all the misconceptions my students have about place value and really gets them thinking about our number system. I will definitely continue using this throughout the year as a way to ensure my students are constantly thinking about place value! A fantastic app which should definitely be used in a classroom

I love this app

You learn a lot in this game and it is loads of fun at the same time, and even if you get the math question wrong they encourage you to try again. There are different parts of math in the stage so you can work on the math that you are having a challenge with. So this is a game that helps you with all sorts of math equations.
