# 3.OA.B.5 Lesson Plans

Apply properties of operations as strategies to multiply and divide. 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 property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.) (Students need not use formal terms for these properties.)

## Coherence Map of 3.OA.B.5

The Coherence Map shows the relationships among the Common Core Standards. The Lumos coherence map not only provides graphical representation and convenient navigation within the standards map but also access to thousands of engaging learning resources such as Practice questions, Videos, Books and Infographics related to every standard. It helps educators and students visually explore the learning standards. It's an effective tool to helps students progress through the learning standards. Teachers can use this tool to develop their own pacing charts and lesson plans.

#### Standard Description of 3.OA.B.5

## TOPICS RELATED TO MULTIPLICATION & DIVISION PROPERTIES

### What are the properties of operations?

There are 4 (four) primary properties of actual numbers: specifically; commutative, associative, distributive and identity. these properties best observe to the operations of addition and multiplication. meaning subtraction and division do not have these properties built in.

### What are the properties of multiplication and division?

Those residences include: the commutative belongings of multiplication, the associative property of multiplication, the identity property of one (multiplying by means of one), the multiplication property of zero, the distributive properties, dividing by using one, department by using 0, 0 because the dividend, and dividing a nonzero quantity by using.

### What are the 3 properties of multiplication?

There are 4 properties related to multiplication with the intention to help make problems simpler to resolve. they're the commutative, associative, multiplicative identity and distributive properties. multiplicative identity belongings: the product of any number and one is that number.
