Grade 3 Unit 13



34823400Students do not need to know the name of the property, but rather understand the process of why it works. Distributive property and associative property are two ways to break apart numbers to multiply. Area is solved by multiplying the lengths. It IS appropriate to talk about parenthesis with students, but is not a requirement for them to use when solving. When finding area, a two digit number can be used as a length of a side. For example 12 x 3, students may see this as 6 x 2 x 3, which is within Grade 3 standards. Using the associatative property they can regroup (6x2)x3 to 6 x (2x3) which is 6x6.00Students do not need to know the name of the property, but rather understand the process of why it works.

Specifically, students will focus on the associative property and explore how and why it works. The associated (grouping) property of multiplication states that the way in which three or more factors are grouped prior to multiplying does not affect the product. The associative property is used to break apart one factor to make a simpler problem that can then be regrouped to solve. They apply this multiplication property and strategy to solve area problems. 00In this unit students will use strategies to multiply whole numbers within 100.

Commutative and Distributive properties have been covered in previous units. The purpose of the first few lessons is to focus on the associative property and how two factors can be broken down to three factors. Similar to what students have learned to Grade 1, these factors can be multiplied in any order to determine the product. This skill is applied to solving for area. Students have prior knowledge of using distributive property to solve for area, and now they will further their understanding 00Purpose of the lesson sequence: Students will begin the unit discussing the properties of multiplication.
