Number Bond Subtraction, Whole 10

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 fact families worksheets work well as daily practice, homework, or a focused review activity.

Fill in number bonds for the whole 10, then write the matching subtraction facts. A number bond shows a whole on top and its two parts below. Whole minus one part is the other part. The directions on the page read: Write the missing part in the empty circle. Then, write the answer to the subtraction sentence. The answer key shows every answer.

Yes, both. We made it for 1st Grade 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 fact families. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

A fact family is a group of four related addition and subtraction equations that all use the same three numbers (e.g., 3+5=8, 5+3=8, 8−3=5, 8−5=3).

By seeing that subtraction and addition are inverse operations using the same numbers, students can use their addition facts to quickly solve subtraction problems.

Fact families directly support CCSS 1.OA.B.3 (commutative and associative properties) and 1.OA.B.4 (understanding subtraction as an unknown-addend problem).

First graders should subtract within 20 using strategies like counting back, using related addition facts, and making ten (CCSS 1.OA.C.6). They should also understand the relationship between addition and subtraction and solve comparison word problems.

Use number lines and hundred charts to make subtraction visual. Practice fact families (e.g., 3+4=7, 7-4=3) to show how addition and subtraction are connected. Start with subtraction within 10 before moving to larger numbers. Consistent daily practice with worksheets builds confidence.
