Skill Progression

This worksheet follows a gradual release model. It begins with foundational problems and builds toward complexity, ensuring learners solidify their understanding.

• Guided Practice: Part 1 introduces the concept with 9 straightforward regrouping problems.
• Supported Practice: The next two parts offer 18 problems to build confidence.
• Independent Practice: The final "Challenge Problems" include 3 questions to test mastery.

This "I Do, We Do, You Do" structure scaffolds the learning process.

Standards Alignment

This worksheet directly aligns with CCSS.MATH.CONTENT.2.NBT.B.5, which requires students to "fluently add... within 100 using strategies based on place value." These tasks specifically target addition with regrouping. It also supports CCSS.MATH.CONTENT.2.NBT.B.9. Both codes can be copied into lesson plans.

How to Use It

Use this after a lesson on 2-digit regrouping for independent work, homework, or a math center. For formative assessment, observe if students consistently carry the "1" to the tens column. Most will finish in 20-30 minutes.

Who It's For

Designed for second graders, this worksheet can also serve as review for third graders or an extension for advanced first graders. For students needing support, pair it with a place value chart or base-ten blocks.

Mastering multi-digit computation, as targeted by standard CCSS.MATH.CONTENT.2.NBT.B.5, is a critical predictor of later math achievement. This worksheet provides the focused practice necessary for students to develop efficient, place-value-based strategies. Research has consistently shown that procedural fluency is essential for freeing up cognitive resources to tackle more complex problem-solving. According to the RAND AIRS (2024) report, sufficient practice is a key component of effective mathematics instruction. By providing 30 sequenced problems on 2-digit addition with regrouping, this resource helps students develop the automaticity needed to confidently engage with higher-level mathematical concepts and meet grade-level expectations.
