Coloring Pencils (Part 2) (Use the number line to calculate a fraction of a whole)

The video tutorial explains how to calculate 2/3 of 15 by dividing 15 into three equal groups and taking two of those groups. It uses Alicia's coloring pencils as an example and demonstrates the solution using a number line. Both methods yield the same result, showing that 2/3 of 15 equals 10. The lesson concludes by summarizing the methods and emphasizing the use of a number line to calculate fractions.

How can you find 2/3 of 15 using groups?

• Divide 15 into two groups and take one group.

• Divide 15 into five groups and take three groups.

• Divide 15 into four groups and take two groups.

• Divide 15 into three groups and take two groups.

What is the first step in using a number line to find 2/3 of 15?

• Divide the number line into five equal parts.

• Divide the number line into four equal parts.

• Divide the number line into three equal parts.

• Divide the number line into two equal parts.

On a number line, where does the second group end when finding 2/3 of 15?

• At 5

• At 15

• At 20

• At 10

What is the result of 2/3 of 15 using both methods discussed?

• 10

• 20

• 15

• 5
