Understanding Division and Distributive Property

This video tutorial from Cohesion Education explains how to use multiplication to solve division problems by employing inverse operations and the distributive property. It provides step-by-step examples, addresses common errors, and offers tips for effective problem-solving. The lesson emphasizes understanding through models and encourages practice for mastery.

What is the main focus of this lesson?

• Using division to solve multiplication problems

• Using subtraction to solve addition problems

• Using multiplication to solve division problems

• Using addition to solve multiplication problems

What are inverse operations?

• Operations that are the same

• Operations that are opposite of one another

• Operations that are identical

• Operations that are unrelated

What does the distributive property do?

• Combines two smaller numbers into a larger number

• Divides a number by another number

• Breaks a larger number into two smaller, easier numbers

• Multiplies two numbers together

In the example of 64 divided by 4, what is the first step?

• Add 64 to 4

• Divide 64 by 2

• Break 64 into two smaller numbers

• Multiply 64 by 4

What two numbers is 64 split into in the example?

• 20 and 44

• 40 and 24

• 50 and 14

• 30 and 34

In the example of 108 divided by 6, what is the first number used?

• 20

• 30

• 10

• 40

What is the second number used to split 108 in the example?

• 48

• 58

• 68

• 78

What is a common error when using the distributive property?

• Not splitting the larger number into two multiples of the divisor

• Adding the numbers incorrectly

• Multiplying the numbers incorrectly

• Using the wrong divisor

How can students check if their split numbers are correct?

• By writing out the multiples of the divisor

• By using a calculator

• By guessing

• By asking a friend

What should students do if they find it difficult to recall multiples?

• Ask the teacher for the answer

• Give up

• Create a list of multiples to refer to

• Skip the problem
