Understanding Fractions on a Number Line

This lesson covers fraction addition and subtraction using number lines and area models. Students learn to label number lines, add and subtract fractions, and compare different models. Practice problems reinforce the concepts, and the lesson concludes with a summary of key points.

What is the first step when labeling a number line for fractions?

• Start with the smallest fraction

• Label the fractions randomly

• Start with the largest fraction

• Begin with zero
