Rainbow Pebbles is a construction toy and early mathematics manipulative that powerfully inspires children to build and investigate. Kids react to the sight of them as if they’ve stumbled upon treasure, which, from a play and learning standpoint, they have. Shape-wise, Rainbow Pebbles strongly resemble natural pebbles and stones one might find along the seashore. But their vivid colors and stunningly smooth surfaces convey that these pebbles were made for playing. The first thing youngsters do is gleefully run their hands over them, hefting them, delighting in the tactile experience. Then the investigations begin – sorting, counting, stacking, arranging, building. 20 included activity cards display a wide variety of critters and objects that can be constructed, a leap-off point for the infinite and highly imaginative possibilities Rainbow Pebbles put at kids’ fingertips. Includes 36 pebbles in 6 colors and 6 sizes.
