Practice that builds confidence
What children learn
These Class 6 maths worksheets strengthen addition and subtraction fluency through missing-number problems. Children practise finding an unknown addend, minuend, subtrahend, or difference in equations such as 36 + ___ = 91 or ___ - 28 = 47.
The printable activities include focused practice for Subtraction Missing Number, Missing Addend Problems 1, and Missing Addend Problems 2. Tasks encourage children to choose the right inverse operation, show working neatly, and check whether the completed equation is true.
This collection moves beyond simply adding or subtracting the numbers given. Children learn to read the whole equation, identify the missing part, and decide which operation will reveal it. In missing addend questions, they connect addition and subtraction: if 24 + □ = 60, then 60 - 24 gives the missing addend. In subtraction missing-number questions, they think carefully about whether the blank is the starting number, the number taken away, or the answer.

Progression across the worksheets
Missing Addend Problems 1 builds confidence with direct addition equations where one part is unknown. Missing Addend Problems 2 gives broader practice with blanks in different positions and encourages flexible thinking. Subtraction Missing Number develops the related idea of unknowns in subtraction statements, helping children understand terms such as addend, sum, minuend, subtrahend, difference, and inverse operation.
A simple parent routine
Ask your child to circle the missing part before solving. Then have them say the relationship aloud: “I know the total and one addend, so I subtract,” or “I know the difference and the subtrahend, so I add.” After each answer, they should place the number back into the original equation and check it by calculating both sides. This short routine builds accuracy without turning practice into memorisation.

Classroom uses for teachers
Teachers can use these sheets for warm-ups, revision after teaching inverse operations, small-group intervention, or independent maths centres. A useful approach is to display one example, ask pupils to name the role of the blank, and then let them complete a set. For discussion, pupils can compare two methods: using a number line jump, writing a fact family, or using column addition/subtraction for larger numbers.

Common errors to watch for
Many children automatically subtract whenever they see a blank, even when addition is needed. Others mix up the minuend and subtrahend in equations like □ - 19 = 43. Watch for careless copying of numbers, missing place values in column work, and answers that are not checked in the original sentence. Encourage estimation so a child can notice when an answer is far too small or too large.

Answers and answer key support
After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The questions are organised around one clear skill at a time, then gradually vary the position of the missing number. This helps Class 6 learners build confidence before facing mixed problems. A child-friendly strategy is: spot the blank, name the known parts, choose the inverse, solve, and check. Repeating this pattern turns missing-number questions into logical puzzles rather than guesswork.
Helpful answers
Frequently asked questions
What skills do these Class 6 addition subtraction worksheets practise?
They practise finding missing numbers in addition and subtraction equations, especially unknown addends, missing minuends, missing subtrahends, and missing differences.
How should my child solve a missing addend problem?
They should identify the total and the known addend, then subtract the known addend from the total. For example, in 38 + □ = 95, they solve 95 - 38.
Why do subtraction missing-number problems feel harder?
The blank can appear in different roles. In □ - 16 = 52, the missing number is the starting number, so addition is used. In 73 - □ = 29, the missing number is the amount taken away, so subtraction is used.
Are these worksheets useful for revision before algebra?
Yes. Missing-number equations prepare children to think about unknown values, inverse operations, and balanced number sentences, which are important foundations for algebra.
How can I help my child avoid sign errors?
Ask them to read the equation in words, circle the blank, and check the answer by substituting it back into the original problem. This prevents automatic or careless operation choices.
Is this Class 6 addition subtraction worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 6 addition subtraction worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this Class 6 addition subtraction worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
