Adding Fractions with Equal Denominators on the Number Line

This lesson teaches how to add fractions using a number line. It uses the example of 3/8 and 2/8, showing how to represent each fraction on separate number lines by dividing the space into equal parts based on the denominator. The lesson then demonstrates how to add these fractions by joining the distances on a single number line, resulting in the sum of 5/8. The video concludes with a recap of adding fractions with equal denominators.

How do you represent the fraction 3/8 on a number line?

• Divide the line into 8 parts and count 3 spaces

• Divide the line into 3 parts and count 8 spaces

• Divide the line into 3 parts and count 3 spaces

• Divide the line into 8 parts and count 8 spaces

What is the first step in representing the fraction 2/8 on a number line?

• Divide the line into 8 equal parts

• Count 8 spaces from the start

• Count 2 spaces from the end

• Divide the line into 2 parts

When adding fractions on a number line, what must be true about their denominators?

• They must be equal

• One must be larger

• One must be smaller

• They must be different

How do you find the sum of 3/8 and 2/8 on a number line?
