3rd Grade Templates: Bunny Hops for Counting On

If your child or your classroom keeps getting 27 + 3 = 29 on a number line, the problem may not be the addition fact at all, and for many PreK-5 teachers, parents, and homeschoolers, the small fix is helping students understand that 27 is the place to start, not the first hop. Bunny hops for counting on is a number-line routine where a child starts on the addend already named, makes one forward hop for each number being added, and says only the landing numbers. It matters because the starting number is not counted as hop 1.

Why bunny hops for counting on works

Counting on works because it turns addition into an action a child can see, say, and touch. In 27 + 3, your child does not need to recount all 27. They can hold 27 in their head, or point to it on the number line, and then count the three new numbers: 28, 29, 30. That tiny language shift from count the numbers to count the hops can clear up a lot of mistakes.

This also lines up with how early addition is described in the Common Core State Standards for Mathematics. Grade 1 standard 1.OA.C.5 connects counting to addition and subtraction, Grade 2 standard 2.MD.B.6 uses number line diagrams for addition and subtraction, and Grade 3 standard 3.NBT.A.2 expects students to add and subtract fluently within 1,000 using strategies based on place value, properties of operations, or the relationship between addition and subtraction. Even if you do not use Common Core in your school or homeschool, those progressions describe a very real path many children travel: count all, count on, then use more efficient strategies.

The visual support matters, too. The Institute of Education Sciences practice guide Assisting Students Struggling with Mathematics: Intervention in the Elementary Grades recommends explicit, systematic math instruction that uses visual representations and clear teacher modeling. A number line gives your child a place to point, a direction to move, and a way to check whether the final answer makes sense. If you are concerned that your student still needs the number line in 3rd grade, remember that tools are not a problem when they are helping a child notice structure and grow toward independence.

Practical Strategies

1. Start on the larger number

When students solve 27 + 3, have them place a finger, counter, or pencil tip directly on 27 before any hopping begins. Say the routine the same way each time: start on 27, hop 3 times, say the landing numbers. On the hops, your child should say 28, 29, 30, because 27 is the starting spot, not hop 1.

The Hop-to-It Addition Easter number line printable is a good fit for this because the bunny hopping forward gives a friendly visual cue. The printable includes six single- and double-digit addition problems where students start on the largest number and count forward hops to find the answer. For the free download, families and teachers need to sign up with an email and join the newsletter, so it helps to know that before you sit down to print.

2. Say the landing numbers

A lot of counting-on errors happen because students say every number they see instead of every number they land on. For 27 + 3, saying 27, 28, 29 gives only two forward moves after 27, which is why the answer comes out too small. Have your child tap the table or clap only when the bunny lands, then say 28, 29, 30 out loud.

A simple classroom prop like a plastic Easter egg can make this feel concrete without making it babyish. Put the egg on 27, slide or hop it to 28 and say 28, then to 29 and say 29, then to 30 and say 30. If your child is in a PreK-5 classroom, at the kitchen table, or learning through homeschool lessons, the same talk pattern helps: start silent, land and say.

3. Mark each hop

Some students need to see the hop count separate from the numbers on the line. Have your child draw a small arc from 27 to 28 and write a tiny 1 above that arc, then draw the next arc to 29 with a tiny 2, and the last arc to 30 with a tiny 3. Now the child can see that the numbers said aloud are 28, 29, 30, while the hop labels are 1, 2, 3.

For a concrete tool, use a Crayola crayon or a highlighter and ask students to make each hop a different color. In a hypothetical worked example like 18 + 4, the child would start on 18, then mark four hops landing on 19, 20, 21, and 22. The color does not matter as much as the matching: four arcs for plus 4, not four spoken numbers starting with 18.

4. Compare the wrong path

It can be helpful to show the mistake without shaming it. Draw a Two Paths T-Chart on a whiteboard or sheet of paper. On one side, write 27, 28, 29 and label it starts by counting 27; on the other side, write 28, 29, 30 and label it counts three hops after 27.

Then ask a checkable question: how many hops did the first path actually make after 27? Your child can point and see that 27 to 28 is one hop and 28 to 29 is two hops, so the first path only moved 2 spaces. This keeps the conversation focused on the number line evidence instead of on being right or wrong, which is much calmer for a child who is already unsure.

5. Connect hops to equations

After a child solves with bunny hops, bring the answer back to the equation. Write 27 + 3 = 30, then circle the 3 and the three hop arcs in the same color. This helps your child understand that the second addend tells how many hops to make, not which number to say first.

If you want more practice with the same idea, choose one page from the number-line addition worksheets collection and use it as a focused counting-on check rather than a full packet. You might say, on each problem, point to the start, count the hops, and tell me the landing numbers. If you need a broader lesson sequence, the how to teach number-line addition guide can support your instruction, while this activity stays focused on the specific mistake of counting the starting number as hop 1.

6. Practice briefly and revisit

Short, repeated practice usually works better than a long correction session. Try three problems at a time, such as 8 + 5, 14 + 2, and 27 + 3, and listen for whether your child says the starting number out loud as part of the count. If they do, gently reset: finger on the start, first hop lands on the next number.

A small sticky note can become your reminder tool. Write Start, hop, land on it and place it near the printable, math notebook, or dry-erase board. You might notice the mistake fade quickly for some students and linger for others, and that is normal; the goal is steady, accurate movement, not rushing them away from the number line before they are ready.

Tips for Accuracy

• Ask your child to point to the starting number silently before saying any numbers aloud.
• Use the phrase first hop lands on the next number when 27 is accidentally counted as hop 1.
• Keep the second addend visible, because +3 means three hops, not three numbers spoken starting at 27.
• Have students draw hop arcs before writing the answer when they are still mixing up starts and landings.
• Move from large printed number lines to blank number lines only after your child can explain why 27 + 3 lands on 30.

Examples

Hypothetical activity: 27 + 3 Bunny Check Write 27 + 3 on a dry-erase board and place a small bunny eraser or counter on 27. Your child hops to 28, 29, and 30 while saying only those landing numbers, then writes 27 + 3 = 30.

Hypothetical activity: Egg Hop Error Hunt Show two solved paths for 16 + 4: one that says 16, 17, 18, 19 and one that says 17, 18, 19, 20. Ask your child to count the spaces after 16 in each path and choose the one with four true hops.

Hypothetical activity: Three-Problem Spring Warm-Up Choose one problem from the Hop-to-It Addition printable and two from your number-line addition worksheet folder. Have your child use the same words each time: start on the bigger number, hop the second number, land on the sum.

Final Thoughts

You do not need a complicated lesson to fix this counting-on mistake. You need a clear routine, a visible number line, and enough calm repetition for your child to notice that the start is a place, not a hop. When you keep the language simple and the practice short, students can build accuracy without feeling stuck. -Adrianna | AAKollective
