Operations and Algebraic Thinking

3.OA.1Interpret and demonstrate products of whole numbers. (MP.1, MP.5)3.OA.2Interpret and demonstrate whole-number quotients of whole numbers, where objects are partitioned into equal shares. (MP.2, MP.5)3.OA.3Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays and measurement quantities, by using drawings and equations with a symbol for the unknown number to represent the problem. (MP.1, MP.4)3.OA.4Determine the unknown whole number in a multiplication or division equation relating three whole numbers. (MP.6, MP.7)3.OA.5Apply properties of operations as strategies to multiply and divide. (MP.3, MP.4)3.OA.6Understand division as an unknown-factor problem. (MP.2)3.OA.7Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations. (MP.2, MP.8)3.OA.8Use various strategies to solve two-step word problems using the four operations (involving only whole numbers with whole number answers). Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. (MP.1, MP.4)3.OA.9Identify arithmetic patterns (including patterns in the addition table or multiplication table) and explain them using properties of operations. (MP.3, MP.8)
