Subtract Whole Tens From Whole Tens Missing Number Practice Activities
Grade 2 worksheets for solving missing-number subtraction equations with whole tens, using place value and related facts.
Practice that builds confidence
What the skill builds
These Grade 2 subtraction worksheets help children solve missing-number equations where both numbers are whole tens, such as 70 - __ = 20 or __ - 30 = 40. Students practise thinking in tens instead of counting by ones.
The printable activities include equation frames, visual prompts, and mixed missing-number problems. Children use place value, related addition facts, and tens patterns to find the unknown number accurately.
Subtracting whole tens from whole tens strengthens place-value understanding. Children learn that 80 - 30 can be read as 8 tens minus 3 tens, then recorded as 50. In missing-number problems, the unknown may be the starting number, the amount subtracted, or the difference, so students must understand the meaning of each part of a subtraction equation.
How the practice progresses
These worksheets move beyond simply answering 60 - 20. A child may see 90 - __ = 40, __ - 50 = 30, or 70 - 40 = __. This variety encourages flexible thinking: use a related fact, count by tens, or imagine base-ten rods. Vocabulary such as difference, subtract, minus, equation, and missing number becomes more familiar through repeated use.
A simple parent routine
Start with a quick warm-up: ask, “What is 7 tens minus 2 tens?” Then show one problem and have your child say the equation aloud. For 80 - __ = 30, ask, “How many tens were taken away to get from 80 to 30?” Encourage counting back by tens: 80, 70, 60, 50, 40, 30. Finish by asking your child to check with addition: 30 + 50 = 80.
Classroom uses for teachers
Use these pages for subtraction review, small-group instruction, math centers, or a short independent practice after a mini-lesson on tens. They are also useful for spotting which students can solve standard subtraction but struggle when the blank appears in a different position. Teachers can pair the worksheets with ten-rods, open number lines, or quick oral tens facts.
Common errors and a child-friendly strategy
Watch for children who subtract the smaller digit from the larger digit without reading the equation, such as treating 40 - __ = 70 as possible. Others may write the difference in every blank. A helpful strategy is: “Name the whole, name the part taken away, name what is left.” Then use a tens path to move forward or backward by 10s.

Why iBloom worksheets help
The practice is focused on one Grade 2 subtraction idea, so children get enough repetition without being distracted by mixed operations or regrouping. The missing-number formats build reasoning, not memorization alone, and the clean printable layout gives space for showing tens jumps, drawing rods, or writing related addition facts.
Helpful answers
Frequently asked questions
What does subtracting whole tens from whole tens mean?
It means both numbers are multiples of ten, such as 80 - 30 or 60 - 20. Children can think of the numbers as tens: 8 tens minus 3 tens equals 5 tens.
Why do the worksheets put the missing number in different places?
Changing the blank helps children understand the whole equation. They practise finding the starting number, the amount subtracted, or the difference, rather than only solving the last answer box.
Should my child count backward by ones for these problems?
Counting by ones works but is inefficient. Encourage counting back or forward by tens, using facts like 8 - 3 = 5 to solve 80 - 30 = 50.
What hands-on tools help with this skill?
Base-ten rods, bundles of ten straws, a hundred chart, or an open number line all help children see the tens being removed or added back to check the missing number.
How can I tell if my child is ready for harder subtraction?
Your child is ready when they can solve missing-number whole-tens equations accurately, explain the role of the blank, and check answers with a related addition fact.
