### Learning Objectives

CCSS.Math.Content.3.OA.B.5 Apply properties of operations as strategies khổng lồ multiply and divide. 2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative sầu property of multiplication) Knowing that 8 × 5 = 40 và 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive sầu property)### Guiding Ideas

**Opening Slideshow **

Materials:

Math notebooks and pencils (colored pencils & graph paper are good for this too)

On the slideshow (see Supporting Files) you will find pictures of hostingvietnam.vn math models that show commutative sầu property of multiplication. During the discussion you should talk about:

a. How these two models are related?

b. What are the number families?

The students should record the following information in their math notebooks:

a. Drawings of the math Model labeled correct equation

b. Number families

Once students students have answered the four questions, unveil the Big Idea:

**Multiplication problems are the same backwards & forwards! **

### Student Activities

**Building the Sky Map**

To phối up the game maps, students enter the hostingvietnam.vn World in Creative sầu mode. Next they will build six math models that show the commutative sầu property of multiplication. So if the first array is 4 x 5 = trăng tròn, their next array will be 5 x 4 = trăng tròn. These math models will be used as the game board và can be strategically used to lớn build bridges lớn opponents’ beds & to defkết thúc your own bed.

Students of the same colored beds are teammates. Encourage them to lớn build strategically together.

No bedrooms: meaning you can not encase your bed in blocks. There must be at least one way in and one way out.

**Peer Đánh Giá **

Tell students we need to kiểm tra our work & to fly around & peer nhận xét your classmates’ math models. After examining the Model, label it with the name of the reviewer and the equation the reviewer saw. If the reviewer saw something different than the creator, there will be different equations. Once all students have sầu labeled at least six math models and differences found in peer nhận xét that have been resolved, start the game.

*Best Practices: have students keep track of their number families by writing notes in their math notebooks. *

**Play trò chơi **

Best Practices: While there is not much doing of math in the section of the lesson plan, it is by far the most important. It is in the game play where they get its meaning, and deeper thinking happens. For example, they will start thinking how lớn use math lớn build strategically. However, the most important part is what it does for the students’ engagement across math. So please give sầu them at least 30 minutes of game play, even if you have khổng lồ break up the lesson inkhổng lồ two days.

For more information on how khổng lồ play the Math Bed Wars mini-game, please see the Supporting Files section.

### Performance Expectations

1. The student was able to lớn build & explain six hostingvietnam.vn math models that show the commutative property of multiplication.

2. The student was able to lớn label their hostingvietnam.vn math models with correct equations on slates.

3. The student was able khổng lồ peer review the hostingvietnam.vn math models & slates of others khổng lồ kiểm tra for accuracy.
