Subtracting 1 Digit From 2 Digit Missing Number No Regrouping Practice Activities
Grade 2 students solve missing-number subtraction equations with a 2-digit number and a 1-digit number, without regrouping.
Practice that builds confidence
The skill in focus
These Grade 2 subtraction worksheets focus on missing numbers in 2-digit minus 1-digit problems with no regrouping. Children practice finding the unknown in equations where one part of the subtraction sentence is left blank.
The printables include open-box equations, related addition thinking, and number sense practice that helps students see how the minuend, subtrahend, and difference work together.
Students work with subtraction situations such as a 2-digit number minus a 1-digit number, with no regrouping needed. The missing number may ask children to find the starting number, the number taken away, or the difference, so they must understand the whole equation rather than simply compute from left to right.
Building from facts to equations
This practice connects basic subtraction facts to 2-digit numbers. If a child knows 8 - 3 = 5, that fact can support 48 - 3 = 45. When the box appears in a different place, students use inverse operations: if 56 - □ = 52, they can think 52 + □ = 56.
A parent routine at home
Choose one problem and read it as a short story: There were 47 stickers, some were used, and 42 are left. How many were used? Ask your child to point to the start, the take-away amount, and the result. Then have them check by adding the difference and the missing subtrahend back together.
Classroom uses for teachers
Teachers can use these worksheets for independent practice, small-group reteaching, math centers, or quick exit checks after modeling open-number sentences. They are also useful for comparing strategies: counting up, using related addition, and subtracting ones while keeping the tens unchanged.
Common errors to watch for
Some students subtract the smaller visible number from the larger visible number without noticing where the blank is. Others regroup even when it is not needed. Encourage children to label the parts: start, take away, left. This keeps the equation meaningful.

Why iBloom worksheets help
The pages give repeated practice with the same structure while changing the position of the missing number. A child-friendly strategy is: Read the equation, name the missing part, solve, then check with addition.
Helpful answers
Frequently asked questions
What does no regrouping mean in these subtraction worksheets?
It means students can subtract the ones without borrowing from the tens place. The focus stays on missing-number reasoning, not regrouping steps.
Which missing numbers do students find?
Problems may ask for the starting 2-digit number, the 1-digit number being subtracted, or the difference, depending on where the blank appears.
How can my child check a missing subtraction answer?
Use addition to check. For example, if 64 - □ = 60, add 60 and the missing number to see whether the sum is 64.
Why are missing-number subtraction problems harder than regular subtraction?
Children must understand the relationship between all parts of the equation instead of only carrying out a subtraction procedure from left to right.
Are these worksheets good for math centers?
Yes. They work well in centers because students can solve, check with addition, and explain which part of the subtraction equation was missing.
Is this Grade 2 missing number subtraction worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Grade 2 missing number subtraction 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 Grade 2 missing number subtraction 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.
