Why is Numberland so fun? It’s because Numberland is a big animated cartoon, but in this cartoon, the child gets to be one of the characters — Stuart! And what’s going on in Numberland? As the children play the games with the cartoon playmates, they earn “brainpower,” which they see filling up Stuart’s brain. When they have enough brainpower, they can use Numberland’s powerful Imagination Machine! This machine turns “imagined” toys into “real” toys, which the children can then sell in Bee’s toy store. So in a nutshell – – they explore and explore, learn how to play games from cartoon playmates, earn brainpower, make toys, sell them to customers, and learn math the whole time…And they never seem to get tired of it!
