Trevor Baisden

K-12 teacher @ 123 School

This is the best math product I've ever tried.


  • Pricing is very accessible.
  • The way kids are driven through the experience in a very intuitive way. They can go through it very independently and the reward system is perfect.


  • Doesn't work on mobile.
