OH.3.OA. OPERATIONS AND ALGEBRAIC THINKING
Understand properties of multiplication and the relationship between multiplication and division.
3.OA.5. Apply properties of operations as strategies to multiply and divide. For example, if 6 × 4 = 24 is known, then 4 × 6 = 24 is also known (Commutative Property of Multiplication); 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30 (Associative Property of Multiplication); knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56 (Distributive Property). Students need not use formal terms for these properties.
OH.3.NBT. NUMBER AND OPERATIONS IN BASE TEN
Use place value understanding and properties of operations to perform multi-digit arithmetic. A range of strategies and algorithms may be used.
3.NBT.2. Fluently add and subtract within 1,000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
