Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
Why water teaches this standard well
Students act out pouring two cups of water into a pitcher and then pouring one back out, using real containers to represent the addition and subtraction physically before it becomes numbers on a page. Ducks joining or leaving a pond are a favorite water scenario for this standard.
Materials tagged with this code are written to the full standard , and each carries a written note explaining the alignment. See how we review materials.
