Cute and engaging! Doesn't require reading. There are no timers or penalties, so the game will wait as long as it takes for the child to figure out the solution. Intuitive interaction with the "nooms" improves intuitive number sense similar to Montessori-style math manipulatives. This is not rote memorization and regurgitation of "math facts" but this program does increase and intuitive understanding of how numbers represent quantities in real life. I have seen a change in how my daughters use their legos and other blocks since starting DragonBox Numbers. My kids don't play this for long stretches of time, but they do keep going back to it on their own. I think they see it as puzzles to solve, which as a scientist and programmer, is aligned with how I personally use and approach math.
