For now there are only these two sheets but I'd love feedback! I'm thinking of developing more. I really liked things like this back when I was in elementary and middle school AND I LOVE the idea of anything that helps students self-check at the end. I feel like by adding that little riddle at the end, the sheet becomes at least a tiny bit more engaging than just the same old/same old sheets we get with our textbooks.
