#### Ohio Learning Standards

OH.K.OA. OPERATIONS AND ALGEBRAIC THINKING
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
K.OA.1. Represent addition and subtraction with objects, fingers, mental images, drawings, sounds such as claps, acting out situations, verbal explanations, expressions, or equations. Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)
K.OA.2. Solve addition and subtraction problems (written or oral), and add and subtract within 10 by using objects or drawings to represent the problem.
K.OA.3. Decompose numbers and record compositions for numbers less than or equal to 10 into pairs in more than one way by using objects and, when appropriate, drawings or equations.
K.OA.4. For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or, when appropriate, an equation.
K.OA.5. Fluently add and subtract within 5.
OH.K.NBT. NUMBER AND OPERATIONS IN BASE TEN
Work with numbers 11–19 to gain foundations for place value.
K.NBT.1. Compose and decompose numbers from 11 to 19 into a group of ten ones and some further ones by using objects and, when appropriate, drawings or equations; understand that these numbers are composed of a group of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
