ASP School Box Our most popular School Box by far and filled to the brim with an amazing assortment of shapes (triangles, squares and rounds) as well as a variety of Balsa wood sheets and Blocks. There is enough wood in this box to keep the whole class busy making and decorating their projects for hours. Perfect for STEAM class engagement, the material in this box can be use to solve engineering problems or design and construct bridges and buildings or create planes and robots. All that needs to be added is a little imagination and some class room basics like scissors, glue and paint. Most items in the ASP School Box are 450mm long but we add a few interesting bits and pieces of shorter material when we have them available!
