This Grade 4 mathematics worksheet helps students practice completing addition and subtraction fact families with missing numbers. Across 10 multiple-choice questions, students read related addition and subtraction equations, identify the value that belongs in the blank, and use the relationship between the operations to choose an answer. The items include equations with totals and differences within 19, giving students focused practice with whole-number facts. Use this resource for independent practice, a short skills check, review after modeling fact families, or targeted work with students who need reinforcement connecting addition and subtraction. Encourage students to examine the known addends, sum, and difference before selecting an option rather than relying on guesswork. This is a free printable worksheet with a complete answer key, and it is also available in a digital format through Wayground.

FAQs
What does the Addition and Subtraction Fact Families worksheet cover?
This Grade 4 worksheet uses 10 multiple-choice questions to practice finding missing numbers in related addition and subtraction equations. Students identify the blank in equations such as a subtraction sentence followed by a related addition sentence, building fluency with how the operations connect within a fact family.
How can I use this worksheet to teach addition and subtraction fact families?
First model how the same three numbers can be connected by addition and subtraction, then solve one of the worksheet’s missing-number equations aloud by identifying the known total, addend, or difference. Have students explain why each answer choice does or does not complete both parts of the displayed relationship before assigning the remaining multiple-choice items for guided or independent practice.
What mistakes should I watch for when students complete this fact families worksheet?
Students may select a number they see in the equation without checking what belongs in the blank, especially when the blank appears after a subtraction sign or addition sign. Watch for confusion between a missing addend and a missing difference, and ask students to substitute their choice back into the displayed equation before finalizing an answer.
How do I assign and grade this addition and subtraction worksheet?
The worksheet is available as a printable PDF and as a digital quiz on Wayground, with a complete answer key for all 10 multiple-choice questions. For printable submissions, you can scan student work with the Wayground for Teachers app to support faster grading and review.
How can I differentiate this fact families worksheet for my students?
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the addition and subtraction equations and answer choices are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options support access to the missing-number practice.
