Subtract Whole Tens From Whole Tens Missing Number Practice Activities
Class 2 worksheets for finding missing numbers in subtraction facts where both numbers are whole tens, such as 80 - __ = 30 or __ - 40 = 20.
Practice that builds confidence
What this skill builds
These Class 2 maths worksheets help children practise missing-number subtraction with whole tens. Instead of only solving 70 - 20, children also find the unknown part in equations such as 90 - __ = 50 and __ - 30 = 40.
The printable activities use clear number sentences, tens-based facts, and varied blanks so children learn to reason about the minuend, subtrahend, and difference. They are useful for revision after learning subtraction of tens and for building confidence before two-digit subtraction.
Subtracting whole tens from whole tens strengthens place value. Children see 80 - 30 as 8 tens - 3 tens, not as a new fact to memorise. Missing-number questions add an extra thinking step: the blank may be the starting number, the amount taken away, or the answer.
How the practice progresses
Early questions can be read as simple tens facts, such as 60 - 20 = __. The challenge increases when the blank moves: __ - 20 = 50 asks, “What number is 20 more than 50?” and 80 - __ = 30 asks, “What was taken away?” This variety helps children connect subtraction with addition and understand the meaning of each part of the equation.
A simple parent routine
At home, ask your child to say the equation aloud before writing. Use bundles of ten sticks, ten-rupee groups, or quick sketches of tens rods. For 70 - __ = 40, show 7 tens, cover 4 tens as the part left, and count the 3 tens taken away. Then write 30 in the blank and read the full sentence again.
Classroom uses for teachers
Teachers can use these worksheets for morning maths, subtraction revision, small-group support, or quick checks after teaching whole tens. They also work well in centres: one group can solve with drawings, another can use a number line, and another can explain the related addition fact, such as 40 + 30 = 70.
Common errors to watch for
Some children subtract the visible numbers in any order, so __ - 40 = 20 may become 20 instead of 60. Others forget that each digit represents tens and write 3 instead of 30. Encourage children to label their thinking with “tens” and to check whether the completed equation makes sense.

Helpful answers
Frequently asked questions
What does subtracting whole tens from whole tens mean?
It means subtracting numbers made of tens only, such as 90 - 40 or 70 - 20. Children can think of them as tens facts: 9 tens - 4 tens = 5 tens, so 90 - 40 = 50.
What kinds of missing numbers are included?
The blank may be the answer, the starting number, or the number being taken away, for example 60 - 20 = __, __ - 30 = 40, and 80 - __ = 50.
How can I help my child solve 90 - __ = 60?
Ask what must be taken away from 90 to leave 60. Your child can count back by tens, use tens rods, or think of the related addition fact 60 + 30 = 90, so the missing number is 30.
Why does my child write 3 instead of 30?
This usually means the child is thinking of the digit only, not its place value. Remind them that 90 is 9 tens and the missing answer must also be written as a whole ten, such as 30.
Are these worksheets suitable before regrouping subtraction?
Yes. These activities focus only on whole tens, so they build place-value understanding and subtraction reasoning before children move to more complex two-digit subtraction.
