The Montessori mystery bag:
a handband of velvet, one small silk scarf, a strip of velcro, one small plastic sponge, a child size wool glove, a small wooden measuring spoon.
Two children: one takes out the items from the bag, names only the shape/object and hands them one at a time to a blindfolded child who feels the items and is supposed to name the material.
The blindfolded child is allowed to rub the object against his skin for a better guess.
