Wooden insets - blu & yellow

The blue and yellow wooden insets, originally made of iron, are designed as a material for indirect preparation for writing, because once the child is indirectly prepared to perform all the movements necessary for writing, writing will no longer present any difficulties; moreover, it is a material that allows for gradual conquests to be made independently, because with the repetition of the exercise, the outlines become parallel and the filling lines no longer come out of the outlines. Indirectly, this material also serves the purpose of educating the colour sense, and provides help in understanding geometric drawing.
