This dinosaur-themed boxed was a huge hit with my 3 yr-old daughter, who loves dinosaurs and can't get enough of them! She sat down and did ALL the activities in one sitting. The arts and crafts were all manageable for her age group with minimal supervision from parents. She particularly loved the masks and cardboard cut-outs she could paint and has incorporated them into her play-time activities. We added some new dinosaur knowledge as well with the thoughtful fact and picture sheets. This was one of our favorite boxes so far and we can't wait to receive more!
