This set of Montessori puzzles comprises of two puzzles. Each puzzle has 3 pieces. The first is a puzzle with a blue circle, a yellow triangle and a red square. The second puzzle has three blue circles, one small, one medium and one large.
Each piece has a large knob on the centre to help the young baby/toddler grasp the pieces using the three-fingergrip. Initially the child may only remove the pieces and later on will become interested in replacing the pieces.
I would demonstrate this material to the child without any words and later you can introduce the language for the different shapes.
