Subtracting Decimals 1 2 Digit Missing Minuend Subtrahend Practice Activities
Class 5 maths worksheets for finding missing minuends and subtrahends in 1- and 2-digit decimal subtraction problems.
Practice that builds confidence
Understanding the missing number
These Class 5 maths worksheets help children practise subtracting decimals when either the minuend or the subtrahend is missing. Learners use place value, decimal alignment and inverse operations to complete equations such as □ − 2.4 = 3.1 or 6.75 − □ = 2.20.
The printable activities include focused decimal subtraction questions with blanks in different positions. Children learn to decide whether to add or subtract to find the missing number, check their answers, and build confidence with tenths and hundredths.
In decimal subtraction, the minuend is the number we subtract from, the subtrahend is the number being taken away, and the difference is the answer. When the minuend is missing, children can add the subtrahend and the difference. When the subtrahend is missing, they subtract the difference from the minuend. This page focuses on those two forms, not just routine vertical subtraction.
Building decimal place-value accuracy
Children practise lining up decimal points so tenths are compared with tenths and hundredths with hundredths. They may need to write 4.5 as 4.50 before subtracting or checking. This helps them see that decimals are numbers with place value, not just digits around a dot. The work is especially useful after children have learnt basic decimal addition and subtraction.
A simple routine for parents
Choose a small set of problems and ask your child to first name the missing part: “Is the starting number missing, or the number taken away?” Then let them write the matching rule: missing minuend = subtrahend + difference; missing subtrahend = minuend − difference. After solving, ask them to put the answer back into the original equation and read it aloud.
Classroom uses for teachers
Teachers can use these printables for independent practice, revision after decimal subtraction lessons, maths centres, or quick checks before moving to word problems. They also work well for pair discussion: one child solves, while the other explains whether addition or subtraction was needed. The blank-position format reveals whether pupils understand the structure of subtraction.
Common errors to watch for
A common mistake is subtracting every time, even when the missing number is the minuend. Some pupils also ignore zero placeholders, misalign decimal points, or mix up the subtrahend and the difference. Encourage children to estimate first: in 7.8 − □ = 2.6, the missing number must be less than 7.8, so an answer greater than 7.8 cannot be correct.

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 iBloom activities keep the focus tight: one skill, varied examples, and enough repetition to make the inverse relationship clear. A child-friendly strategy is: “Find the blank, name the parts, choose the operation, then check in the original sentence.” This turns missing decimal subtraction into a logical puzzle rather than guesswork.
Helpful answers
Frequently asked questions
What is the missing minuend in decimal subtraction?
The minuend is the starting number in a subtraction sentence. If it is missing, children add the subtrahend and the difference, for example □ − 2.4 = 3.1 becomes 2.4 + 3.1 = 5.5.
How does a child find a missing subtrahend?
The subtrahend is the number being taken away. To find it, subtract the difference from the minuend, such as 6.75 − □ = 2.20, so 6.75 − 2.20 = 4.55.
Why do children need to line up decimal points?
Lining up decimal points keeps the place values matched. Tenths must be worked with tenths and hundredths with hundredths, otherwise the subtraction can give an incorrect answer.
Should children add zeros to decimals while solving?
Yes, when helpful. Writing 4.5 as 4.50 can make hundredths subtraction clearer and prevents children from misplacing digits.
How can parents check if the answer is correct?
Ask the child to place the answer back into the original equation. If the completed subtraction sentence is true, the missing decimal has been found correctly.
Is this Class 5 missing decimal 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 5 missing decimal subtraction worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
