**Lesson:**3.5 Distributive Property

**Subject:**Math

**Grade:**5th

**Integration of Learning Outcomes:**Students will be able to use the Distributive Property to simplify expressions and solve equations by constructing viable arguments and critiquing the reasoning of others, looking for and making use of structure, looking for and expressing regularity in repeated reasoning.

**Standards**

· 5.OA.1

**Procedures**

*Beginning:*

· Watch enVision 3.5 Distributive Property video. Pause and ask questions along the way.

· Watch Study Jams Distributive Property video. Show “Watch Out.” Complete “Try It Out.”

· Watch Study Jams Distributive Property video. Show “Watch Out.” Complete “Try It Out.”

*Middle*

· PBIL: (Post Image/Questions on Active Inspire) What is one way to show the number of squares? How many rows are there? How can you represent the number of columns left? One expression is 8 x (10-4). To write another expression, think of subtraction in terms of whole and parts. How can you find the total number of squares? How can you find the number of squares being subtracted? A second expression is (8 x 10) – (8 x 4). Do these two expressions have the same value? How are the expressions related to each other?

o Pause
and ask the questions. Students will work in small groups.

o Define
Distributive Property: multiplying a sum or difference by a number is the same
as multiplying each number in the sum (or difference) by that number and adding
(or subtracting) the products

· How would you rewrite (8 x 5) – (8 x 2) using the distributive property
o Answer:
8 x (5-2)

· Complete independent and guided practice

*End*

o Picture
1 (Picture 2 + Picture 3) = (Picture 1 x Picture 2) + (Picture 1 x Picture 3)

· Play distributive property matching game**Differentiation**

· Two different videos for two different ways of showing (students can pick method they liked the best)

· Picture/visual/models for visual learners

· Picture/visual/models for visual learners

**Formative/Summative Assessment**

· End-of-unit test

· Observations

**Materials/Technology**

· enVisions Math 3.5 Distributive Property Video

· Study Jams Distributive Property Video

· ActivInspire

· Distributive Property Match Game

**Reflection on Instruction:**

Students really did not get the distributive property at
first. They couldn’t figure out that
they are just writing out the factors that they are multiplying. They wanted to solve the whole thing. They could solve the problem using other
methods, but they basically refused to use the distributive property. I kept doing practice problems with
them. By the end, most were able to pick
up that they were just writing out the factors.

I didn’t get to show the distributive property visual, but
this may help for review. I would like to make a visual for each of the
properties, since we did not get a chance to do it with the other properties. I
should make a poster with all the properties using pictures. This may make for
a good review.

For homework, we decided to use a worksheet that laid out
parenthesis. This way, repeated process
would engrave that they are jus multiplying factors for the distributive
property.
