Associativity and Multiplication Problems (Part 1)

The video tutorial explains how to solve multiplication problems using different methods. It starts with simple multiplication sentences like 8 times 2 and progresses to more complex ones like 16 times 3. The tutorial highlights the limitations of using a multiplication table and introduces the associative property to simplify calculations. By regrouping factors, the video demonstrates how to efficiently solve problems and avoid errors.

What is the result of multiplying 8 by 2?

• 10

• 12

• 14

• 16

If a multiplication table only goes up to 9, how can you calculate 16 times 3?

• Multiply 16 by 9

• Add 16 three times

• Use a calculator

• Divide 16 by 3

What property allows you to group factors differently without changing the result?

• Identity Property

• Commutative Property

• Distributive Property

• Associative Property

What is the result of 2 times 3?

• 8

• 6

• 5

• 7

Using the associative property, what is the result of 8 times 2 times 3?

• 36

• 42
