The reason I invited DreamBox Learning to be a sponsor is that I was impressed with the games in so many ways. As you probably know, I've been working in educational curriculum and training design for a long time, and currently work for another video game company on a freelance basis.
So I've seen a ton of educational software. Most of it breaks down into "we took this fun game and slapped some math into it" or "we took these math worksheets and added some animation to them." The first one ends up being fun but not educational, and less fun than other games the kids could be playing. The second one ends up being Not Fun and the kids don't want to do it.
DreamBox, though, is really well designed. Really. The games are designed around mathematical concepts that are age-appropriate, and the whole concept and situation of the game comes from the math. The games are designed with the understanding that math itself is fun and interesting, so replicating natural situations and creating games out of them is better and more effective than adding sparkle to camoflage math in the first place. It makes the games intuitive for kids, and the concepts build naturally, just the way they do in real life.
If you've been resisting checking out DreamBox because you've ssen the bad math games out there, just do a free trial and you will see the huge difference a well-designed game makes.
