Our biggest school build to date, for a local preschool. Playing on this structure is as easy as A, B, C - or, if practicing our counting, it's: 2 (castles with bubble windows and climbing walls) + 1 (scramble net) + 1 (bridge) + 3 (play platforms) + 6 (rope hooks) + 1 (trapeze rope) + 1 (swinging bar) = a whole lot of fun!!! Maybe not mathematically correct but this was the verdict of two Little House Littles when they tested it out (even thought they are bigger than the preschoolers in question!).
