Adding Whole Hundreds Thousands Missing Addend Practice Activities
Class 4 maths worksheets for finding missing addends in addition equations using whole hundreds and whole thousands.
Practice that builds confidence
What children learn
These Class 4 maths worksheets help children find the missing addend in addition facts with whole hundreds and whole thousands. Learners read equations such as 2,000 + ___ = 5,000 or ___ + 300 = 900 and work out the unknown part, not just the final sum.
The printable activities include fill-in-the-blank number sentences, horizontal and vertical addition, related-fact practice, and short word problems. Each sheet builds confidence with place value, mental addition, and checking by subtraction.
A missing addend question asks, “What number must be added to make the total?” In this topic, the numbers are friendly place-value amounts: whole hundreds and whole thousands. Children connect addition and subtraction, so 4,000 + ___ = 9,000 can be solved as 9,000 - 4,000 = 5,000.
How the practice progresses
The worksheets begin with simple hundred facts and thousand facts, then mix the unknown position: ___ + 600 = 1,000, 3,000 + ___ = 8,000, or ___ + 2,000 = 6,000. Children also meet vertical layouts where the blank may appear in an addend row, helping them see that place values must line up before calculating.
Parent routine at home
Choose one page and ask your child to read each equation aloud using the words “part, part, whole”. Let them circle the total, underline the known addend, and say the related subtraction before writing the answer. After every few problems, ask, “How can you check it?” The check should be the original addition sentence.
Classroom uses for teachers
Use these printables for addition revision, maths centres, morning practice, or quick assessment after teaching place value addition. Pair children to sort questions into “hundreds” and “thousands”, then ask them to explain one solution on the board using a number line, base-ten language, or a related subtraction fact.
Common errors to watch for
Some children add the two visible numbers even when one is the total. Others ignore zeros and answer 5 instead of 5,000. Watch for misaligned digits in vertical sums and for answers that are larger than the total when they should be a missing part. Encourage estimation: if the total is 7,000, the missing addend cannot be 9,000.

Why iBloom worksheets help
iBloom activities keep the numbers clear while varying the equation form, so children do not memorise a pattern. A child-friendly strategy is: “Find the whole, take away the part, then check by adding.” This simple routine supports mental maths, place-value understanding, and accuracy with missing-number addition.
Helpful answers
Frequently asked questions
What is a missing addend in Class 4 addition?
A missing addend is the unknown number being added in an equation. For example, in 2,000 + ___ = 6,000, the missing addend is 4,000.
How should children solve missing addends with whole thousands?
They should identify the total, subtract the known addend, and then check by adding. For 8,000 - 3,000, the missing part is 5,000, so 3,000 + 5,000 = 8,000.
Do these worksheets include both hundreds and thousands?
Yes. The practice focuses on addition equations using whole hundreds such as 400 or 900 and whole thousands such as 2,000 or 7,000.
Why do children sometimes write 5 instead of 5,000?
They may be thinking only about the leading digit and forgetting place value. Ask them to say the full number aloud and check whether the answer is in hundreds or thousands.
Can these worksheets be used for revision before larger addition sums?
Yes. Missing addend practice strengthens place value, mental subtraction, and checking skills, which are useful before moving to longer multi-digit addition.
