Exam board: Common Core
A set of two-step riddles to be used to teach the inverse between doubles and halves.I would suggest printing them out on different colors to allow the children to self assess their own ability and try harder ones if they want to challenge themselves! Aligned with Common Core State Standards: 3.OA.1, Operations and Algebraic Thinking. Adapted from a resource contributed to TES Connect by lydiacook2
