Subtraction within 20 (no borrowing)

Before handing out the worksheet, briefly introduce the concept with a short oral warm-up or a visual model on the board. Encourage students to talk through their thinking as they work: "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 subtract within 20 no borrow worksheets work well as daily practice, homework, or a focused review activity.

These subtract within 20 no borrow worksheets for Kindergarten 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 subtract within 20 no borrow from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for Kindergarten. Practicing subtract within 20 no borrow at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

"Subtraction within 20 (no borrowing)" is written for Kindergarten (Ages 3-6), and it covers Common Core K.OA.A.5. Extends beyond the standard: K.OA.A.5 covers fluency within 5, this worksheet works within 20. If your little one is a year younger but already steady on subtraction, the page still works. You may just need to read the instructions out loud. And if they are older and subtract within 20 no borrow never quite stuck, this is a short review rather than busywork.

Yes, both. We made it for Kindergarten subtraction, 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 subtract within 20 no borrow. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

These worksheets include any subtraction problem with a result between 0 and 20, but every problem is structured so that no digit in the top number is smaller than the corresponding digit below - eliminating the need to borrow. This makes them harder than within-10 worksheets but more accessible than full two-digit subtraction.

Working with numbers up to 20 without borrowing builds number fluency and familiarity with teen numbers, which underpins the 1st grade standard 1.OA.C.6 (add and subtract within 20). Children who are comfortable here find the transition to regrouping in 2nd grade much smoother.

If your child can quickly and accurately solve subtraction problems within 10 and can identify and count teen numbers confidently, they are likely ready. Watch for frustration with counting larger numbers - if they struggle, return to within-10 practice and come back to these worksheets in a few weeks.

Kindergarteners should understand subtraction as taking apart or taking from. Per CCSS K.OA.A.1, they should represent subtraction with objects, drawings, and equations within 10. Fluency is expected within 5 (K.OA.A.5).

Start with concrete objects: give your child 5 crackers and ask them to eat 2, then count what remains. Use visual worksheets that show crossed-out items before introducing number sentences. The key is connecting the physical act of removing to the minus sign.

Most children find subtraction more challenging because it requires understanding that a group is getting smaller. Research suggests introducing subtraction alongside addition so students see them as related operations. Worksheets that pair addition and subtraction facts help build this connection.
