A must have Sorting Wagon.

Mega Bloks Building Basics Shape Sorting Wagon set has a sorter, a game that each baby has to master. The benefits of any shape-sorter set are immense. Baby/toddler start to learn to classify, begin to develop the hand-eye coordination and problem-solving skills.
At the begging toddlers just pushing the shapes anywhere their hand can reach, but with little parent's help, they will get the idea how to use it.

In general Mega Blocks is one of the must-have toys that any toddler has to have among his/her toys for its unquestionable benefits in terms of the development of gross and fine motor skills, imagination, ability to play, creativity and many more.

From what I observed while watching my kids playing with mega-blocks over the years I can tell that this toy is a great educational tool that helps toddlers to develop different skills and raise their intelligence.
