Partitioning a Number Line to Locate Fractions

The video tutorial teaches how to partition a number line to locate fractions. It explains the concepts of numerator and denominator, and demonstrates how to partition the line into equal parts using a paper strip. The tutorial guides viewers on plotting fractions and locating specific points, such as three-fourths, on the number line.

What is the first step in using a number line to locate a fraction?

• Identify the whole number.

• Identify the unit fraction.

• Draw the number line.

• Label the endpoints.

What does the denominator in a fraction represent?

• The number of highlighted parts.

• The total number of parts.

• The starting point on the number line.

• The number of whole units.

How can you accurately partition a number line into fourths?

• By guessing the midpoint.

• By using a ruler.

• By folding a paper strip twice.

• By drawing random lines.

What is the purpose of using a paper strip in partitioning?

• To mark the starting point.

• To ensure equal partitioning.

• To label the fractions.

• To measure the length of the number line.

What is the starting point on a number line when locating fractions?

• 3/4

• 1

• 1/4

• 0

How do you represent the whole number 1 in terms of fourths?

• 4/4

• 3/4

• 2/4

• 1/4

What fraction is located at the halfway point on a number line divided into fourths?

• 1/4

• 2/4

• 3/4

• 4/4

What should you do after plotting the starting and ending points on the number line?

• Fold the paper strip again.

• Label the remaining fractions.

• Erase the number line.

• Draw a new number line.

How do you indicate the location of 3/4 on the number line?

• By erasing it.

• By boxing or circling it.

• By drawing a new line.

• By folding the paper strip.

What is the final step in using partitioning to locate a fraction?

• Draw a new number line.

• Box or circle the fraction.

• Fold the paper strip.

• Erase the number line.
