Recently I've sound a site, where it is described, how to use LEGO to teach kids about simple math. You can even learn multiplying and division with those small plastic bricks. How awesome is that?
More to that: this construction toy helps to improve motor functions, imagination, xommunication skills, etc.
It also improves reading skills, as it is crucial to use the instructions.
I believe, that LEGO is a great education tool. And it is great, that teachers throughout the country understand that as well.
