Our pre-school children had a great time exploring and digging for dinosaur bones in our tuff top trays. They were then able to introduce mathematical concepts into their play as the counted their finding and lay them in order of sequence from the smallest to largest bones. Using the all about dinosaurs fact finding books they were able to predict which bones belonged to different dinosaurs!! Our outdoor tuff top trays contained diggers and sand...and our baby trays contained water and water toys for a truly splashing time! we all had great fun!
