Multiplication as a Comparison: Using Number Sentences

The video tutorial explains how multiplication can be used as a comparison by using number sentences and bar models. It begins with an introduction to the concept, followed by a review of a previous lesson using bar models. The core lesson focuses on writing multiplication equations for 'seven times as many as four' and 'four times as many as seven', both resulting in the product of 28. The tutorial concludes with a final example of 'five times as many as six', resulting in 30. Throughout the lesson, the use of bar models helps visualize the multiplication process.

What is the result when you multiply four groups of two?

• 6

• 8

• 10

• 12

How can you express seven times as many as four using a multiplication equation?

• 7 x 4 = 28

• 7 + 4 = 11

• 4 x 7 = 28

• 7 - 4 = 3

If you have four times as many as seven, what is the product?

• 21

• 24

• 28

• 32

What multiplication equation represents five times as many as six?

• 6 - 5 = 1

• 5 + 6 = 11

• 6 x 5 = 30

• 5 x 6 = 30

Which of the following statements is true about multiplication as a comparison?

• It compares groups of numbers

• It involves dividing numbers

• It is unrelated to bar models

• It is always addition
