The expensive Insets used by the Montessori School can be
satisfactorily made out of heavy cardboard and accomplish the desired
result. Take a piece of cardboard of good thickness and draw on it some
of the figures illustrated above. After they are cut out with a sharp
knife, smooth the edges so that they will fit easily into the places
from which they came. The cardboard from which they are cut may be
fastened to another or tacked to a thin board. The game is to blindfold
the child, give him the cutouts and by the sense of touch let him find
the proper hole and fit the piece into it. As the pieces are fitted
into their places they may be left there until the board is filled.
This exercise is a little more difficult than most of the others.
Encourage the child to keep at it.
