Subtracting 2 Digit Numbers Missing Numbers No Regrouping Practice Activities
Grade 1 worksheets for finding missing numbers in 2-digit subtraction equations without regrouping, using tens and ones thinking.
Practice that builds confidence
What this skill builds
These Grade 1 subtraction worksheets help children solve 2-digit subtraction problems where one number is missing and no regrouping is needed. Children practise reading equations carefully, using place value, and deciding whether the missing part is the starting number, the number taken away, or the answer.
The printable activities include horizontal and vertical subtraction formats, tens-and-ones reasoning, and missing boxes in different positions. Each page keeps the numbers friendly so children can focus on the unknown number rather than borrowing.
Missing-number subtraction strengthens the idea that subtraction is a relationship, not just a take-away action. A child may see 58 - __ = 34, __ - 12 = 45, or 76 - 24 = __. Because there is no regrouping, the ones digit can be subtracted directly and the tens digit can be compared or subtracted with confidence.
How the worksheets progress
The practice moves from clear 2-digit subtraction facts to equations with the blank in different places. Children learn to look at the whole equation before calculating. They use vocabulary such as minuend, subtrahend, difference, tens, ones, and missing number in a grade-appropriate way.
A simple parent routine
At home, choose a few problems and ask your child to read each equation aloud. Have them circle the missing box, underline the known numbers, and say what they need to find. For 64 - __ = 31, they can compare 64 and 31: 4 ones became 1 one, so 3 ones were taken away; 6 tens became 3 tens, so 3 tens were taken away. The missing number is 33.
Classroom uses
Teachers can use these printables for small-group reteaching, morning work, math centers, or independent practice after a place-value subtraction lesson. They are also useful for checking whether students understand the role of each number in an equation instead of only following a vertical subtraction routine.
Common errors to watch for
Some children subtract the smaller digit from the larger digit in each column without thinking about the equation. Others fill the blank with the difference every time, even when the missing number is the starting number or the number being taken away. Encourage students to ask, “Does my number make the equation true?” and to check by substituting their answer back into the original problem.

Why iBloom worksheets help
iBloom worksheets keep the focus narrow: 2-digit subtraction, missing numbers, and no regrouping. The clean layouts reduce distraction, while varied blank positions encourage flexible thinking. A child-friendly strategy is: find the blank, work with ones, work with tens, then check the full equation.
Helpful answers
Frequently asked questions
What does no regrouping mean in these subtraction worksheets?
No regrouping means children do not need to borrow from the tens place. The ones and tens can be subtracted or compared directly.
What kinds of missing numbers are included?
The blank may be the starting 2-digit number, the number being subtracted, or the difference, so children practise understanding the whole equation.
How can my child check a missing subtraction answer?
They should put the number back into the blank and solve the equation again. If both sides make sense, the missing number is likely correct.
Are these worksheets suitable for children just learning 2-digit subtraction?
Yes, because the problems avoid regrouping and support tens-and-ones thinking, which is appropriate for early 2-digit subtraction practice.
Why are missing-number problems useful in Grade 1?
They help students see subtraction as a relationship between numbers and prepare them for fact families, equations, and later algebraic thinking.
