Editors' Notes

Imagine a strategy game crossed with an math primer, and you’ve got DragonBox Big Numbers. By trading apples and other resources, kids can explore a gorgeous landscape as they learn addition and subtraction concepts. We’re impressed by how seamlessly the app combines play and learning. From drawing digits to solving ingenious visual math problems, numbers are fun in countless ways.

Very good

I learned lots of math from this it would be five stars if the last thing you had to do cost 54321 coins!? But it is very good and your children will benefit from this. I rate it 9/10
