Enter the total number of students in the class.

Step 1: To choose the winning class, you will compare fractions. Start with Class A.

- Enter the total number of students in the denominator (the bottom part) of the first fraction.
- Click on “Plot on Number Line” and see how the number line changes.

Step 2: Continue with Class A.

- Click on each student who has blown a bubble and see how the number line changes.
- With each click, the numerator (the top part) of the fraction increases by one. The point on the number line moves forward by one-sixth each time.

Step 3: Now, do the same for Class B.

- Enter the total number of students in Class B as the denominator of the second fraction.

- Click on “Plot on Number Line” and see how the number line changes.

Step 4: Continue with Class B.

- Click on each student who has blown a bubble.
- With each click, the numerator increases by one. The point on the number line moves forward by one-eighth each time.

Step 5: Which class won the contest?

- Compare the two number lines and choose the winner.

Step 2: Continue with Class A.

- Click on each student who has blown a bubble and see how the number line changes.
- With each click, the numerator (the top part) of the fraction increases by one. The point on the number line moves forward by one-tenth each time.

Step 3: Now, do the same for Class B.

- Enter the total number of students in Class B as the denominator of the second fraction.

- Click on “Plot on Number Line” and see how the number line changes.

Step 4: Continue with Class B.

- Click on each student who has blown a bubble.
- With each click, the numerator increases by one. The point on the number line moves forward by one-eighth each time.

Step 5: Which class won the contest?

Step 4: Continue with Class B.

- Click on each student who has blown a bubble.
- With each click, the numerator increases by one. The point on the number line moves forward by one-sixteenth each time.

Step 5: Which class won the contest?

- Compare the two number lines and choose the winner.
