Complete the next ten

Written by Adi Ackerman, Head Teacher

"Complete the next ten" is written for 1st Grade (Ages 6-7), and it covers Common Core 1.NBT.C.4. If your little one is a year younger but already steady on addition, the page still works. You may just need to read the instructions out loud. And if they are older and complete the next ten never quite stuck, this is a short review rather than busywork.

How do I use this worksheet?

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Let students work through the first item together as a class, then finish the rest independently or with a partner, encouraging them to talk through their thinking: "What strategy are you using? How do you know that is right?" After completing the worksheet, review any missed problems together and discuss the reasoning rather than just the answer. For extra support, let students use manipulatives or draw pictures alongside the written problems. These complete the next ten worksheets work well as daily practice, homework, or a focused review activity.

What does this worksheet teach?

⌄

These complete the next ten worksheets for 1st grade give students the structured, hands-on practice they need to build confidence and fluency. Students work through a range of problem formats, from visual models and diagrams to written equations and word problems, so they encounter complete the next ten from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 1st grade. Practicing complete the next ten at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

Can I use this complete the next ten worksheet for homeschool or classroom?

⌄

Yes, both. We made it for 1st Grade addition, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with complete the next ten. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

What mental math skill does 'complete the next ten' build in 1st grade?

⌄

It builds the ability to find the distance to the next decade, which is the first step in the 'jump to ten' strategy for two-digit addition.

How does this skill connect to number bonds for 10?

⌄

Completing the next ten uses the same partners-to-10 logic - the ones digit of the given number needs to be paired with its partner to reach the next round ten.

Can this skill be practiced on a number line for visual learners?

⌄

Yes - marking the starting number and the next ten on a number line makes the 'jump' visible, helping students count or calculate the gap.

What addition facts should a first grader know?

⌄

By the end of first grade, students should fluently add within 10 (CCSS 1.OA.C.6) and solve addition problems within 20 using strategies like counting on, making ten, and decomposing numbers. They should also add within 100 using place value understanding (1.NBT.C.4).

How do you teach first graders to add double-digit numbers?

⌄

Start with adding a two-digit number and a one-digit number, then progress to two two-digit numbers. Use place value understanding: add the tens first, then the ones. Base-ten blocks and place value worksheets make this concrete before moving to abstract equations.

What are addition strategies for first grade?

⌄

Key strategies include counting on from the larger number, making a ten (e.g., 8+5 becomes 8+2+3), using doubles (6+6=12) and near-doubles (6+7=6+6+1), and decomposing to known facts. Worksheets that practice each strategy separately help students build fluency.
