1st Grade Subtraction Number Line Worksheet: Match the Hops

Ask a six-year-old to walk backward along the hallway tiles, one step at a time, and they will often count the tile they stand on as the first step. This 1st grade subtraction number line worksheet works on that same slip, with paper instead of tiles. Each of the four colored boxes holds a number line from 0 to 10. Small curved hops, each marked -1, jump backward from one number to another, and four subtraction sentences wait underneath. Your child counts the hops, finds where they start and stop, and marks the one sentence that matches. A green caterpillar sits on the first box. A second page gives the answer key.

Why counting back is a real strategy

Cubes show subtraction as taking away. A number line shows it as moving: you start at one number and count back to another. Both ideas matter, and first graders need to see that they give the same answer.

The page is honest about this. Every hop carries a small -1, so the child can read each jump as one step back. For example, in the top box, the hops start at 9 and land on 5.

Also, the choices are close cousins. The first box offers 9 - 5 = 4, 9 - 4 = 5 and 9 - 3 = 6, so a quick guess fails. Your child must count the hops on a number line and check where they begin, then pick the subtraction sentence that tells the same story. That matching step is the point.

At the table: seven hops in the purple box

Begin with the blue box. Ask your child to touch the first hop with a finger and say, "Where do these hops start and stop?"

The purple box is the hardest, with seven hops from 10 down to 3. A child may count the numbers instead of the jumps, and land on eight. Instead of correcting, slide a fingertip along each curve and say, "One hop, then another." Counting the arcs, not the numerals, usually fixes the gap.

In the orange box, the choices 8 - 6 = 2 and 9 - 7 = 2 share an answer. Ask, "Which number did the hops start from?" Your child can point to the start of the first arc and decide alone. Then the tick goes in.

Hopping backward at home

A number line becomes easy once the body has walked one. Tape ten squares of paper on the floor, number them, and let your child hop backward from 9 while you both count the jumps out loud. Then, on the stairs, start on step 8 and walk down six steps.

Also, Hopscotch is a ready-made number line. Chalk the boxes, play a round, then try hopping back from the top and saying where you land.

These small games keep subtraction within 10 in the legs as well as the head. When you finish, check the page with the answer key and praise the work itself: "You traced every hop. That is careful counting back."
