Grapat rainbow cups with lids are a fantastic heuristic play material. They can be used by infants for discovery and sensory games. Later they become containers to help children develop logical-mathematical thinking by classifying, organising, grouping, matching, etc. The game seems simple but simple things become complex if we are allowed to explore the multiple possibilities of non-structural elements.

Combine them with other loose parts, sets of nins or a tinker tray and the play possibilities are endless. 

Great to add to your loose parts and open ended play collection.

Recommended age 10+ months.
