Strand: NUMBER AND OPERATIONS IN BASE TEN (3.NBT)
Use place value understanding and properties of operations to perform multi-digit arithmetic. A range of algorithms may be used
(Standards 3.NBT.1-3).
Standard 3.NBT.3
Multiply one-digit whole numbers by multiples of 10 in the range 10-90 (for example, 9 x 80 and 5 x 60) using strategies based on place value and properties of operations.

Grade 3 Unit 2: The Relationship Between Multiplication and Division (Georgia Standards)
In this unit, students will begin to understand the concepts of multiplication and division, learn the basic facts of multiplication and their related division facts, apply properties of operations (commutative, associative, and distributive) as strategies to multiply and divide, understand division as an unknown-factor problem. For example, find 32 8 by finding the number that makes 32 when multiplied by 8. Fluently multiply and divide within 100, using strategies such as the patterns and relationships between multiplication and division, understand multiplication and division as inverse operations, solve problems and explain their processes of solving division problems that can also be represented as unknown factor multiplication problems and represent and interpret data.
