A Child's first building set designed to expand the learning experience obtained from playing with our popular TALL-STACKER PEGS and PEGBOARD and take it to the next level... LITERALLY!! This three dimensional stacking set teaches children to think ahead as they plan where they will set the Tall-Stacker Pegs to build the next platform as well as teach shape, size and color relationships. As with our original peg sets, children continue to build their fine-motor and math skills.
