Missing addends (3 terms)

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 multi-digit addition worksheets work well as daily practice, homework, or a focused review activity.

These multi-digit addition worksheets for 5th 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 multi-digit addition from every angle. Each worksheet is designed to build on prior knowledge while introducing the level of challenge appropriate for 5th grade. Practicing multi-digit addition at this stage strengthens the mathematical foundations that support more advanced concepts in later grades.

This worksheet is designed for 5th Grade students (Ages 10-11), aligned to Common Core standard 5.NBT.B.7. It can also be used as review for early students at the next grade level or as an introduction for advanced students.

Yes. This worksheet works for homeschool, classroom, and tutoring settings. Print individual pages for targeted practice, or print the full set as a packet. Works great as a morning warm-up, independent center activity, or fast-finisher task.

Fifth grade addition focuses on adding decimals to hundredths (CCSS 5.NBT.B.7), adding fractions and mixed numbers with unlike denominators (5.NF.A.1), and applying addition in multi-step word problems. Students should also apply the associative and commutative properties to simplify complex expressions.

Per CCSS 5.NF.A.1, students must find a common denominator before adding. The most reliable method is finding the least common multiple of both denominators, converting each fraction, then adding numerators while keeping the denominator. Mixed number addition also requires converting improper fractions in the answer. Worksheets that show the steps explicitly help students internalize the procedure.

The key is aligning decimal points so that tenths align with tenths and hundredths with hundredths. This is the same logic as aligning ones with ones in whole-number addition. Encourage students to use graph paper or lined worksheets to keep columns aligned. CCSS 5.NBT.B.7 covers this skill, and estimation with compatible numbers is an important check on answers.
