Here are some great sites for exercising your brain!

Invention at Play has four different activities.

      Cloud Dreamer lets you make your own cloud and then watch it move across the sky.

       Puzzle Blocks gives you three different puzzles to put together, and it isn't as easy as it looks!

       Tinker Ball is really cool because you have to build a machine to get a ball into a cup.

       Word Play gives you a word bank so you can add on to a story about inventing.
