Multiplication as Resizing (Part 2)

The video tutorial explains how to use scale factors to predict the size of figures after resizing. It uses examples, such as resizing a garden, to illustrate how a scale factor greater than one increases size, while a factor less than one decreases it. The lesson concludes by reinforcing the concept of interpreting multiplication as resizing with a scale factor.

What happens to the size of a figure when a scale factor greater than one is applied?

• The figure becomes larger.

• The figure remains the same size.

• The figure disappears.

• The figure becomes smaller.

If you multiply a number by a scale factor greater than one, what can you say about the product?

• The product is zero.

• The product is less than the original number.

• The product is equal to the original number.

• The product is greater than the original number.

In the example of multiplying 12 by 3 1/2, what role does 3 1/2 play?

• It is the scale factor.

• It is the product.

• It is the original size.

• It is the divisor.

What is the effect of a scale factor less than one on the size of a figure?

• The figure becomes larger.

• The figure remains the same size.

• The figure becomes smaller.

• The figure doubles in size.

When multiplying 8 by 3/5, what can be concluded about the product compared to 8?

• The product is greater than 8.

• The product is equal to 8.

• The product is less than 8.

• The product is zero.
