What's on the worksheet
Draw the jumps on the number line. Then write the answer. The first one is done for you.
Look at the jumps. Write the addition they show.
Solve 5 + 9 two ways on a number line: start at 5, then start at 9. Which way takes fewer jumps? ★
Skills practiced
A number line turns addition into movement: start at the first number and hop to the right once for each number you add. On this page your child draws the jumps for four sums within 20, then works backward, reading jumps that are already drawn and writing the matching addition. This is counting on, a key first grade strategy, made visible. A final challenge shows that 5 + 9 and 9 + 5 land in the same place, though one way takes far fewer jumps.
Your child reads the instruction out loud and explains in their own words what to do.
Work through the tasks in order: the first ones are easier and warm up for the next.
The task with a star is optional, for early finishers.
Check together with the answer key and redo only what was wrong.
Tips for parents and teachers
Remind your child that the starting number is not a jump: put the pencil on the first number, then count 1, 2, 3 with each hop. Landing one space too far, because the start was counted as a jump, is the most common mistake on this page. Saying the numbers aloud while hopping (7, 8, 9) helps a lot. A paper strip on the floor with the numbers 0 to 20 makes a great life-size version.
Make it easier or harder
Easier: Use a line from 0 to 10 and sums within 10 at first, and let your child hop a small toy along the line before drawing the arcs.
Harder: Ask your child to show 8 + 7 by jumping to 10 first and then the rest, or to use the same line to subtract by jumping to the left.

1Draw the jumps on the number line. Then write the answer. The first one is done for you.
6 + 3 = 9
9 + 4 = 13
12 + 5 = 17
7 + 6 = 13
2Look at the jumps. Write the addition they show.
8 + 5 = 13
11 + 7 = 18
3Solve 5 + 9 two ways on a number line: start at 5, then start at 9. Which way takes fewer jumps? ★
Both ways land on 14. Starting at 9 is faster: only 5 jumps instead of 9.
