2-Digit Addition With Regrouping Worksheet | Grade 2

Introduction: What Students Will Practice

Adding two-digit numbers is a big step in second grade, and regrouping is the skill that makes it work. This 2-digit addition with regrouping worksheet for Grade 2 gives students 240 printable questions to practice trading 10 ones for 1 ten.

Students move from Easy to Advanced practice and then apply the same skill to everyday word problems. Every section has 30 questions, and a complete answer key sits at the end. Parents, teachers, tutors, and homeschool families can print only the pages they need and check work quickly.

How to Use These Worksheets 2-Digit Addition With Regrouping Worksheet

Getting Started

• Print the sections you need. Each one works as a stand-alone worksheet.
• Ask students to write their name and the date at the top.
• Begin with Easy, then move to Medium, Advanced, and Mixed as confidence grows.
• Allow base-ten blocks, quick drawings, or a place value chart for extra support.
• Check answers with the Answer Key only after the work is finished.

Worked Example

Try 38 + 27 with the class and say each step aloud:

• Add the ones: 8 + 7 = 15. Write 5 in the ones place and regroup 1 ten.
• Add the tens: 3 + 2 + 1 (the regrouped ten) = 6 tens.
• Write the sum: 65.

Tips for Adults

Remind students to add the regrouped ten. Ask them to explain their steps in words, which supports the reasoning described in standard 2.NBT.B.9. Short daily practice usually works better than one long sitting.

Skills Covered

• Adding two-digit numbers when the ones digits make 10 or more
• Regrouping 10 ones as 1 ten
• Adding a one-digit number to a two-digit number
• Finding missing digits and missing addends in addition equations
• Comparing sums with >, <, and =
• Adding three or four two-digit numbers
• Finding sums over 100
• Solving addition word problems and writing the unit

Relevant Common Core Standards

• NBT.B.5: Fluently add within 100 using strategies based on place value and properties of operations.
• NBT.B.6: Add up to four two-digit numbers using place value strategies.
• NBT.B.7: Add within 1000 using place value strategies, and understand that a ten or hundred is sometimes composed. This supports the sums over 100.
• NBT.B.9: Explain why addition strategies work, using place value and properties of operations.
• OA.A.1: Use addition and subtraction within 100 to solve one- and two-step word problems.

This post focuses on addition. Missing-addend questions connect to the relationship between addition and subtraction named in 2.NBT.B.5. Totals over 100 go past the within-100 limit of 2.NBT.B.5 and 2.OA.A.1, so teachers may treat them as enrichment tied to 2.NBT.B.7.

Frequently Asked Questions

What is regrouping in 2-digit addition?

Regrouping, also called carrying, means trading 10 ones for 1 ten. In 38 + 27, the ones make 15, so students keep 5 ones and move 1 ten to the tens column.

Which students is this worksheet best suited for?

It is written for Grade 2 students who already know basic addition facts and place value. Younger or older learners can also use the Easy and Advanced sections for review or challenge.

Do students need base-ten blocks?

No, but blocks, drawings, or a place value chart help students who are still learning why regrouping works. The goal is to move toward written strategies over time.

How can I help a student who forgets the regrouped ten?

Have the student write the small 1 above the tens column before adding the tens. Then ask them to say the tens addition aloud: 3 + 2 + 1.

How many questions are included?

There are 240 questions in total: 30 in each of four practice sections and 30 in each of four word problem sections.

Conclusion

Regular practice with regrouping builds the confidence students need for three-digit addition and subtraction. Print the sections that fit your learner, work through the Answer Key together, and come back to Math Obsession for more Grade 2 math worksheets.
