## Topic 3

## Multiplying by 10 and 100 Properties Lesson 3-1 & 3-2 Students must determine products of a number and 10 or 100 using properties of operations and place value understandings. (4.4B) | ## Multiplying by Multiples of 10 and 100 Lesson 3-3 & 3-4Students use strategies and algorithms, including the standard algorithm, to multiply up to a 4 digit number by 1 digit and 2 digit by 2 digit. Strategies may include mental math, partial products, and the commutative, associative, and distributive properties (4.4D) | ## Breaking apart to Multiply Lesson 3-5 |
