These engaging, double-sided stones feature a raised footprint of an animal on one side and an image of the animal on the other side. Press the footprint into sand, mud or soil and create a trail for children to follow. They can record their findings by taking rubbings, making impressions in dough, creating prints using paints and much more. Large 3" stones are safe for use by children ages 2 and up. Each set contains 8 double-sided stones. Grades PreK+
