Subtract Whole Tens From 2 Digit Numbers Practice Activities
Class 2 printable maths practice for subtracting whole tens from 2 digit numbers using place value, counting back by tens, and clear number sentences.
Practice that builds confidence
Understanding the skill
These Class 2 maths worksheets help children practise subtracting whole tens, such as 20, 40 or 70, from 2 digit numbers. Children learn to reduce the tens part of a number while noticing when the ones digit stays unchanged.
The printable activities include number sentences, place-value thinking, and mixed practice with examples like 68 - 30 and 94 - 50. They support children as they move from counting back by tens to solving mentally with tens and ones.
Subtracting whole tens from a 2 digit number is a key Class 2 subtraction step. Children work with numbers that have tens and ones, then subtract a number with zero ones. In 76 - 40, the 4 tens are removed from the 7 tens, and the 6 ones remain 6. This builds vocabulary such as tens, ones, whole ten, digit, difference and number sentence.
How the learning progresses
Early practice often begins with seeing the tens clearly: 58 is 5 tens and 8 ones. Children then connect this to counting back by tens: 58, 48, 38 after subtracting 20. As confidence grows, they solve directly by thinking, “5 tens minus 2 tens is 3 tens, so 58 - 20 = 38.” The worksheets give repeated practice so children can recognise that subtracting 10, 20, 30 and other whole tens changes the tens digit first.
A simple parent routine
At home, choose five questions and ask your child to circle the tens in the number being subtracted. For 83 - 50, say: “83 has 8 tens. We take away 5 tens. What is left?” Let your child write the answer, then check by counting back: 83, 73, 63, 53, 43. End with one oral question, such as “What is 62 minus 30?” to build mental maths.
Classroom use for teachers
Teachers can use these printables for morning practice, small-group support, revision after a place-value lesson, or independent maths work. The questions are useful for checking whether pupils understand the structure of 2 digit numbers rather than only memorising answers. They can also be paired with base-ten blocks, bundles of sticks, number lines or quick tens-and-ones drawings.
Common errors to watch for
Some children subtract from the ones digit by mistake, writing 76 - 40 as 72 or 36. Others count back by ones instead of tens, which is slow and can lead to slips. A useful child-friendly strategy is: “Look at the zero. Subtract tens, keep the ones, then check.” Encourage children to say the full sentence: “I took away 4 tens.”

Helpful answers
Frequently asked questions
What does subtracting whole tens from a 2 digit number mean?
It means taking away a number such as 10, 20, 30 or 40 from a 2 digit number. For example, in 67 - 30, children subtract 3 tens from 6 tens and keep the 7 ones.
Why does the ones digit often stay the same in these questions?
A whole ten has zero ones, so the ones are not being reduced. In 84 - 50, the tens change from 8 tens to 3 tens, while the 4 ones remain 4.
Should my child count back or use place value?
Both methods are useful. Counting back by tens helps children see the pattern, while place value helps them solve more quickly by subtracting tens from tens.
What mistake should I look for during this practice?
Watch for children subtracting from the ones digit or changing both digits without thinking. Ask them to explain how many tens were taken away to check understanding.
How can these worksheets be used after a Class 2 subtraction lesson?
They work well as independent practice, revision homework, or small-group support after teaching tens and ones. Children can also solve a few questions orally before writing.
