Malleable fun for investigation and exploration, building up strength in hand tendons and muscles making them ready for scissor control. Squashing, squeezing, rolling, flattening, chopping, scoring, poking and extruding all uses fine motor skills, hand eye coordination and concentration. As loose parts are included, experiences and benefits continue to grow. Objects from nature with different textures and shapes add to the multisensory experience and a plethora of mathematical opportunities emerge to sort, compare and estimate lengths, weights and lump sizes. The scientific process of making playdough involves questioning and prediction skills; observing with fascination, the changing state of unrelated ingredients as they form a ball of dough.
