Subtract Whole Tens From Whole Tens Practice Activities
Grade 2 subtraction worksheets that help children subtract whole tens from whole tens using place value, counting back by tens, and number patterns.
Practice that builds confidence
What children are learning
These Grade 2 math worksheets focus on subtracting whole tens from whole tens, such as 70 − 30 or 90 − 50. Children practise seeing tens as groups, not just digits, so subtraction becomes a place-value idea rather than memorized guessing.
The printable activities include clear subtraction problems, visual and mental-math practice, and opportunities to notice patterns in the tens place. They are useful for classwork, centers, homework, review, or extra practice before moving into two-digit subtraction with ones.
Subtracting whole tens from whole tens helps children understand that numbers like 40, 60, and 80 are made of groups of ten. In problems such as 80 − 20, the child is really thinking, “8 tens minus 2 tens equals 6 tens,” so the answer is 60. This supports stronger place-value understanding for later two-digit subtraction.
How the practice progresses
The worksheets keep the numbers focused on whole tens, which lets children concentrate on the tens place. They may solve facts like 50 − 10, 70 − 40, and 100 − 60, then notice that the subtraction fact 7 − 4 can help with 70 − 40. Some activities encourage mental subtraction, while others can be paired with base-ten blocks, ten rods, number lines, or quick drawings of tens.
A simple parent routine
At home, ask your child to read the problem aloud first: “90 minus 30.” Then have them say it in tens: “9 tens minus 3 tens.” Let them solve, write 60, and explain how they knew. For a quick check, invite them to count back by tens from the larger number: 90, 80, 70, 60. Keep the routine calm and short, focusing on clear thinking rather than speed.
Classroom uses for teachers
Teachers can use these printables for small-group reteaching, morning work, independent practice, or math centers. They also work well after a mini-lesson with base-ten blocks: students model 60 − 20, remove two ten rods, and record the matching equation. For discussion, ask students to compare 6 − 2 and 60 − 20 and explain what changes.
Common errors to watch for
Some children subtract the digits but forget the zero, writing 4 instead of 40 for 70 − 30. Others count back by ones instead of tens, which is slow and can lead to mistakes. A few may reverse the numbers and solve 20 − 80. Encourage them to circle the larger starting number, underline the tens, and say the equation in tens before answering.

Why iBloom worksheets help
iBloom worksheets give children repeated, focused practice with one skill at a time. The layout supports attention to the operation sign, the tens pattern, and the final answer. A child-friendly strategy is: “Think tens, subtract the tens, write the zero.” For example, 80 − 50 becomes 8 tens − 5 tens = 3 tens, so the answer is 30.
Helpful answers
Frequently asked questions
What does subtracting whole tens from whole tens mean?
It means subtracting numbers that end in zero, such as 60 − 20 or 90 − 40. Children think in groups of ten: 6 tens minus 2 tens equals 4 tens, so 60 − 20 = 40.
Why is this skill important in Grade 2?
It builds place-value understanding and prepares children for subtracting two-digit numbers. When students understand tens as groups, they are less likely to rely only on counting by ones.
How can I help my child if they write 5 instead of 50?
Ask them to say the problem in tens. For 80 − 30, they should say, “8 tens minus 3 tens equals 5 tens.” Then remind them that 5 tens is written as 50.
Should children use manipulatives for these worksheets?
Yes, if they need support. Ten rods, bundled sticks, drawings of tens, or a number line can help children see why 70 − 20 leaves 50.
Can these worksheets be used for mental math practice?
Yes. Because the numbers are whole tens, children can practise solving mentally by subtracting the tens digits and then writing the zero.
Is this subtract whole tens from 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 subtract whole tens from 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.
Does this subtract whole tens from whole tens worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
