This tower encourages fine motor skills by building and balancing the shapes to make a tower.  It develops logical thinking when building as the shapes cause the tower to be straight up or leaning (like the Leaning Tower of Pisa).  The builder must decide which blocks to use where, before the tower falls;  the builder learns about shapes.  The builder is socialising as he/she discussed whic colour and what brick to use.
