Children have so much fun with Rainbow Pebbles, an essential educational toy for early mathematics and construction. These pebbles capture children's imagination, starting with copying activity cards and progressing to creating their own animals, 2D or 3D pictures, and buildings. Through play, children learn counting, sorting, classifying, patterning, sequencing, construction, and stacking. The set includes 36 pebbles in 6 sizes and colors, and 20 activity cards, all in a sturdy plastic container. Suitable for ages 3 and up.
