Here are four number lines. There is a point on each number line.

For each number line, label the point with the fraction it represents. This is your target. Make 2 forward jumps to get from 0 to the target.

• Pick a card from the set given to you. Use the fraction on it for your first jump. Draw the jump and label it with the fraction.
• From that point, draw the second jump to reach the target. What fraction do you need to add? Label the jump with the fraction.
• Write an equation to represent the sum of your two fractions.
