The materials are:
– Bear Stacker: barrier
– Wonderpine: tree for Brachio and Triceratops and other herbivores
– Dinos obviously
– Coffee beans (which we always have): as pebbles
– Blue pasta: as a lake / niche
– Homemade playdough: as sand
For the learning materials, we separated the carnivores and herbivores dino. The carnivores on the outside, and the herbivores on the inside. Our 29 mo son has begun memorizing which ones, so we let him to separate by himself, then we provided corrections and explanations when he mistook.
