Subtract Whole Tens From Hundreds Practice Activities
Grade 2 subtraction worksheets that help children subtract whole tens from hundreds using place value, regrouping, and mental math strategies.
Practice that builds confidence
Build the idea with place value
These Grade 2 subtraction worksheets focus on subtracting whole tens from hundreds, such as 300 - 40 or 700 - 90. Children practise seeing a hundred as 10 tens so they can subtract tens accurately instead of guessing.
The printable activities include clear number problems, place value thinking, and repeated practice with multiples of ten. They help students connect base-ten understanding, regrouping, and mental subtraction in a manageable way.
Subtracting whole tens from hundreds is a small skill with an important idea behind it: sometimes a hundred must be traded for 10 tens. In a problem like 500 - 60, children cannot take 6 tens from 0 tens unless they rename 500 as 4 hundreds and 10 tens. The answer becomes 440. This prepares students for later multi-digit subtraction with regrouping.
How the practice progresses
These worksheets give children repeated chances to work with hundreds and tens without the distraction of ones. Problems may use equations such as 200 - 30, 600 - 80, or 900 - 50. Students can picture base-ten blocks, draw quick tens lines, count back by tens, or use an open number line to move from the hundred to the difference.
A simple parent routine
At home, choose a few problems and ask your child to say what is being subtracted: “How many tens are we taking away?” For 400 - 70, guide them to think, “400 is 40 tens. Take away 7 tens. That leaves 33 tens, or 330.” Then have your child solve two more independently and explain one answer out loud.
Classroom uses for teachers
Teachers can use these pages for subtraction warm-ups, small-group reteaching, math centers, or quick checks after a lesson on regrouping. They also work well with base-ten blocks: students model the hundred, trade one hundred for 10 tens, remove the tens, and record the equation.
Common errors to watch for
Some children write 300 - 40 = 340 because they focus only on the digits. Others may subtract 4 from 3 and ignore place value. Encourage students to use the words hundreds and tens, not just numbers. A helpful child-friendly strategy is: “Trade a hundred, take away tens, then count what is left.”

Helpful answers
Frequently asked questions
What does subtracting whole tens from hundreds mean?
It means taking away a multiple of ten, such as 30, 60, or 90, from a whole hundred such as 200, 500, or 800. For example, 600 - 70 = 530.
Why is this skill important in Grade 2 subtraction?
It helps children understand regrouping. They learn that a hundred can be renamed as 10 tens, which is needed for later subtraction with larger numbers.
Should my child use base-ten blocks for these worksheets?
Base-ten blocks are very helpful at first. Children can build the hundred, trade one hundred for 10 tens, remove the tens being subtracted, and then count the value left.
What mistake is most common with problems like 400 - 50?
A common mistake is treating the digits separately and writing an answer such as 450 or 350 without understanding the regrouping. Encourage your child to think of 400 as 40 tens, then subtract 5 tens.
How can I help my child solve these mentally?
Ask them to convert the hundred into tens. For 700 - 80, think 70 tens - 8 tens = 62 tens, so the answer is 620.
