The questions are amazing, but students feel disheartened when they struggle to read the screen. ### 5/5 — I love this app *2017-04-08* 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.

Very clean design, intuitive and easy to use. The kids love 'zero' and his positive feedback! Loved the growth mindset too. ### 5/5 — Get this app when you teach place value!! *2016-12-31* I used this app with my Year 3 students and it was fantastic for a range of abilities.
