The Imaginarium 150-Piece Wooden Block Set includes 74 natural and 76 colored blocks Extend your child's science content knowledge and math skills with these engaging STEM Learning Tips. 1. Ask your child to stack and count mid-sized blocks of the same size and shape until the tower tips over. Then, do the same with all smaller and then all larger-sized blocks. Which tower was the tallest before it tipped over? Guide your child to see that the height of a tower of blocks and the width of the base affects its stability. Ask your child to notice the direction in which the blocks fall (downward) and understand that the blocks fall downward because of a force (a push or a pull) called gravity. 2. Identifying shapes is a math concept that children learn in their early years. Help your child recognize, name, and sort the shapes of the blocks. Then, go around the house to find objects that are the same shapes. Research has shown that a STEM education gives children the edge in becoming economic and technological leaders of the global marketplace.Toys R Us
