out that many objects.
K.OA.A.1 - Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal

K.OA.A.2 - Solve addition and subtraction word problems, and add and subtract
within 10, e.g., by using objects or drawings to represent the problem.
