Grade 3 Module 3 Lesson 10 Insights

The video tutorial covers the distributive property in multiplication and division. It begins with an introduction to the concept, explaining how breaking numbers into smaller chunks can simplify calculations. The teacher demonstrates this with examples, such as solving 6 times 8 and 7 times 8 using the distributive property. The lesson then transitions to applying the distributive property in division, using number bonds to break down division problems into manageable parts. The tutorial concludes with practice problems and a summary of the learning objectives, emphasizing the efficiency of the distributive property in solving complex arithmetic problems.

What is the main advantage of using the distributive property in calculations?

• To make calculations more complex

• To use more paper and resources

• To simplify calculations by breaking them into smaller parts

• To learn advanced mathematical theories

In the example, how was the multiplication of 6 times 8 simplified using the distributive property?

• By adding 6 and 8

• By dividing 6 by 8

• By breaking it into 6 times 5 and 6 times 3

• By multiplying 6 by 8 directly

What is the result of 6 times 5 plus 6 times 3?

• 15

• 18

• 48

• 30

What is the result of 7 times 8 using the distributive property?

• 56

• 49

• 64

• 42

What is the purpose of breaking a multiplication problem into smaller chunks using the distributive property?

• To increase the number of calculations

• To make it easier to visualize

• To make the problem harder to solve

• To reduce the accuracy of the solution

Why is it beneficial to look for a '5' when using the distributive property in multiplication?

• Because it's easier to multiply by 5

• Because it's a common mathematical practice

• Because it reduces the number of steps

• Because it makes the problem more complex

How is the distributive property applied to division?

• By adding the divisor to the dividend

• By subtracting the divisor from the dividend

• By multiplying the divisor with the dividend

• By breaking the dividend into smaller parts and dividing each by the divisor

In the division example, how was 64 divided by 8 simplified?

• By multiplying 64 by 8

• By breaking it into 40 divided by 8 and 24 divided by 8

• By adding 8 to 64

• By subtracting 8 from 64

What is the result of 40 divided by 8 plus 24 divided by 8?

• 8

• 7

• 9

• 5

What is the result of 72 divided by 8 using the distributive property?

• 7

• 8

• 9

• 10
