Subtracting 1 Digit From Whole Ten Practice Activities
Grade 2 worksheets for subtracting a 1-digit number from a whole ten, helping children bridge tens with regrouping and mental math.
Practice that builds confidence
What this skill builds
These Grade 2 subtraction worksheets focus on taking a 1-digit number away from a whole ten, such as 30 − 6 or 80 − 9. Children practise seeing a ten as 10 ones, then subtracting across that ten with confidence.
The printable activities include clear subtraction problems, visual thinking opportunities, and practice that builds from supported examples to independent work. They are useful for strengthening place value, regrouping, and mental subtraction strategies.
Subtracting a 1-digit number from a whole ten is a small skill with a big place-value lesson inside it. A problem like 40 − 7 cannot be solved by subtracting from the ones digit because there are 0 ones showing. Children learn to trade one ten for 10 ones, then subtract: 40 becomes 3 tens and 10 ones, and 10 − 7 leaves 3 ones, so the answer is 33.
How the worksheets progress
The practice is designed around whole tens such as 10, 20, 30, and beyond, paired with 1-digit subtractors. Early items encourage children to think with tens and ones. Later problems support faster mental math, including the useful pattern: 50 − 8 is the same as 49 − 7 after stepping back 1, or 50 − 8 = 42 because 10 − 8 = 2 and one ten has been regrouped.
A simple parent routine
At home, begin with base-ten language before writing answers. Ask your child to say, “I have 6 tens and 0 ones. I trade 1 ten for 10 ones.” Then solve a few problems aloud, such as 60 − 4 and 20 − 9. After that, let your child complete a short section independently and explain one answer using the words tens, ones, trade, subtract, and difference.
Classroom uses for teachers
Teachers can use these pages for subtraction warm-ups, small-group reteaching, math centers, or quick checks after a place-value lesson. They also work well as follow-up practice after students model regrouping with base-ten blocks or draw quick tens and ones. For partner work, one student can solve while the other checks whether the regrouping step is shown or explained correctly.
Common errors to watch for
Some children subtract the smaller digit from the larger digit and write answers like 30 − 7 = 37. Others forget to reduce the tens after trading, turning 40 − 6 into 44 instead of 34. Watch for children who can recite steps but cannot explain why a ten becomes 10 ones; they may need drawings or manipulatives before moving to mental strategies.

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 problems give focused practice on one exact subtraction situation, so children are not distracted by mixed procedures too early. A child-friendly strategy is: “Break one ten, subtract from 10, then keep the remaining tens.” For 70 − 8, break one ten, solve 10 − 8 = 2, keep 6 tens, and write 62.
Helpful answers
Frequently asked questions
What does subtracting a 1-digit number from a whole ten mean?
It means subtracting numbers like 5, 7, or 9 from a multiple of 10, such as 20, 40, or 90. Examples include 30 − 8 and 70 − 6.
Why is this skill difficult for some Grade 2 students?
The ones digit in a whole ten is 0, so children must understand that one ten can be regrouped as 10 ones before subtracting the 1-digit number.
Should children use drawings or solve mentally?
Both are useful. Drawings or base-ten blocks help children understand the regrouping. Once the idea is secure, they can use mental strategies to solve more fluently.
What is a good strategy for problems like 60 − 7?
Trade one ten for 10 ones. Then solve 10 − 7 = 3 and keep the remaining 5 tens. The answer is 53.
How can I tell if my child understands the concept?
Ask your child to explain a problem using tens and ones. A strong explanation should mention trading one ten, subtracting from 10 ones, and reducing the number of tens by one.
