Abel Blocks are block sets especially designed for toddlers thru two year olds. The four simple shapes of blocks provide the sturdiness needed to learn to balance the blocks successfully. Block building is a small group activity, which promotes social skills as well as an understanding of balance and gross motor skills. To promote social interaction through play, this set is assembled for two to three children. All Abel Blocks are constructed of hardwood and feature rounded edges and smooth-sanded surfaces.
