They are also able to place a block onto a stack of blocks without knocking over the entire tower. By gaining these skills, children are able to pick on one block from a stack without toppling the entire block tower. This occurs on a stability basis (use of the core and shoulder to stabilize the arm) and on a dexterous basis (precise, small, and graded movements of the fingers). Building with blocks helps kids develop graded fine motor skills- As small children progress through typical grasp progression, they begin to gain more control over those motor skills. By picking up on block, manipulating it in the hand, and placing it on a stack of blocks, children progress from a gross grasp to a radial palmer grasp and then to a digital palmer grasp, followed by a tip-to-tip grasp using the pointer finger and thumb.Ĭheck out this developmental checklist for more information.Ģ. Blocks are a fine motor power tool when it comes to working on grasp development! Read below for the specifics of small kids playing with blocks.
