Perfect for memory and sorting activities! Children are naturally drawn to investigating small containers, intrigued and excited by the possibilities hidden inside. Kids collect natural objects or gather everyday items to hide inside the acorns. An activity guide offers memory matching games, peek and describe, exploring scent, hide and seek, sorting, number hunt, spelling games, and related activities. The kit provides 10 acorns with corresponding green or orange lids and a different “clue animal” on the bottom of each. Acorns measure 2½ inches high x 2 inches wide. Recommended for ages 3-6 (small pieces included).
