Science themed educational preschool games
We used giant floor puzzles. We had a pond and a rain forest one. Those are all I can really think of right now.....our little ones liked doing our elementary science curriculum (God's Creation). We also had a body book that we'd glue body parts to that our preschoolers loved to do too. Coloring and cutting, plus laying down and getting their whole bodies traced so they could glue body parts on. Pretty basic.
