Operations and Algebraic Thinking
Understand properties of multiplication and the relationship between multiplication and division.
Apply properties of operations as strategies to multiply and divide. (Students need not use formal terms for these properties.) [3-OA5]
Number and Operations in Base Ten
Use place value understanding and properties of operations to perform multi-digit arithmetic. (A range of algorithms may be used.)
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. [3-NBT2]
