Subtracting Whole Tens Practice Activities
Grade 1 worksheets for practising subtraction with whole tens, using place value, counting back by tens, and simple equations like 70 - 20.
Practice that builds confidence
Understanding subtraction with tens
These Grade 1 subtraction worksheets help children practise taking away whole tens, such as 60 - 20 or 90 - 30. The focus is on seeing each number as groups of ten, not as unrelated digits.
Printable activities include clear subtraction equations, visual models, and practice that supports counting back by tens. Children build confidence with multiples of 10 while strengthening early place value understanding.
Subtracting whole tens is an important bridge between basic subtraction facts and larger two-digit subtraction. Children learn that 80 - 30 means 8 tens minus 3 tens, which leaves 5 tens, or 50. This makes subtraction feel logical because the ones place stays at zero.
How the practice progresses
The worksheets keep the focus on multiples of 10, usually from 10 to 90. Problems may appear as number sentences, missing answers, or visual tens models. A child might solve 70 - 20 by counting back two tens: 70, 60, 50. This repetition helps children connect spoken counting, written numbers, and place value language such as tens, subtract, difference, and fewer.
A simple parent routine
At home, begin with real or pretend bundles of ten, such as craft sticks, linking cubes, or dimes. Show 6 groups of ten and say, “This is 60.” Remove 2 groups and ask, “How many tens are left?” Then write 60 - 20 = 40. After a few hands-on examples, let your child complete a short worksheet section and explain one answer aloud.
Classroom uses for teachers
Teachers can use these printables for independent practice, math centers, morning work, small-group reteaching, or quick checks after a place value lesson. They also work well with base-ten blocks or a hundred chart. Students can solve on paper first, then compare strategies with a partner: Did they count back by tens, use tens rods, or subtract the tens digits?
Common errors to watch for
Some children subtract the ones digits even though both ones are zero, or they may answer 70 - 20 as 5 instead of 50. Encourage them to say the full unit: “7 tens minus 2 tens is 5 tens.” Another common slip is counting back by ones instead of tens. A hundred chart or number line marked by tens can make the jump size visible.

Why iBloom worksheets help
iBloom worksheets give first graders focused, uncluttered practice with one skill at a time. The activities support a child-friendly strategy: look at the tens, subtract the tens, then say the answer as a whole ten. For example, 90 - 40 becomes “9 tens take away 4 tens equals 5 tens, so the answer is 50.”
Helpful answers
Frequently asked questions
What does subtracting whole tens mean in Grade 1?
It means subtracting numbers like 10, 20, 30, or 40 from another multiple of 10, such as 80 - 30. Children think in groups of ten rather than subtracting single ones.
How can I explain 70 - 20 to my child?
Say, “70 is 7 tens and 20 is 2 tens. If we take away 2 tens from 7 tens, 5 tens are left. Five tens is 50.” Using bundled sticks or base-ten rods makes this clear.
Should children memorize these answers?
Fluency is helpful, but understanding should come first. Children should be able to show that 60 - 40 is 20 by counting back by tens or by subtracting tens groups.
What mistakes are common with whole tens subtraction?
Children may write only the tens digit, such as 4 instead of 40, or count back by ones. Remind them to name the answer as tens: 4 tens equals 40.
Can these worksheets be used with manipulatives?
Yes. They pair well with base-ten blocks, tens frames, craft-stick bundles, dimes, number lines, or a hundred chart so children can model each subtraction problem before writing the answer.
Is this Grade 1 subtracting whole tens worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Grade 1 subtracting whole tens worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
