Rainbow kids ,


I had some difficulty at the beginning but now it works well. Maybe they fixed it or maybe I was doing it wrong. I would suggest the developer do an explainer video so parents can understand how to present it.

Lots of ways to practice

So much to love about Montessori but no other developer does it as well as these guys. Intuitive, thorough and an easy, beautiful format. So many ways for my 6 year old to practice adding and subtracting large numbers! The reward system doesn't out do the learning games so it's not a distraction which is a plus in my book. Having an opportunity to practice with manipulatives really solidifies any new concepts that come with adding and subtracting large numbers.

Mmmm...mmm ,

Great app

Nice maths
