We have this math manipulative that we just love. It's called Mighty Mind and comes in a variety of themes. This one is just the general interest one. Though they also have underwater, animals and more. It works on spacial awareness, fractions and patterns. The ages are 3 to 8 and really holds the interest of children in the whole range. My only pet peeve - the box claims "Makes Kids Smarter". I guess everyone wants the next super kid right?
