What's Inside

This resource contains a three-page printable worksheet with 40 vertical addition problems. The layout is clean and spacious, giving students room to work. A complete answer key is provided on a separate page, allowing for quick grading or self-correction. The worksheet is organized into four distinct sections that guide students through the skill.

Skill Progression

The worksheet uses a gradual-release model to build student independence.

• Guided Practice: The first section, "Basic Regrouping," presents 8 problems that introduce the core concept of carrying a ten.
• Supported Practice: The next 12 problems in "Strengthening Skills" offer continued practice with varied numbers, solidifying the regrouping process.
• Independent Practice: The final 20 problems, in "Advanced Challenges" and "Final Mastery," require students to apply the skill independently across a full range of addends.

Standards Alignment

This worksheet is directly aligned with CCSS.MATH.CONTENT.2.NBT.B.5, which requires students to "Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction." It provides focused practice on addition with regrouping. Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use this worksheet as independent practice after a direct instruction lesson on addition with regrouping. It is also effective as a homework assignment to reinforce the day's learning. For formative assessment, circulate as students work on the "Strengthening Skills" section, noting who is consistently carrying the one. The entire worksheet should take most students between 15 and 25 minutes to complete.

Who It's For

This resource is designed for second-grade students learning addition with regrouping. It can also serve as a review for third graders at the beginning of the year or as an intervention tool for students struggling with the concept. Pair with a place value mat for concrete support.

This worksheet provides focused practice on two-digit by one-digit addition, a critical skill outlined in CCSS.MATH.CONTENT.2.NBT.B.5. The standard requires students to add fluently within 100 using place value strategies, and this resource directly supports that outcome through problems requiring regrouping. Research highlights the importance of procedural fluency built upon conceptual understanding. According to the RAND AIRS (2024) analysis, effective practice materials provide sufficient repetition to automate procedures like carrying, freeing up cognitive resources for more complex problem-solving later. The worksheet's 40 structured problems offer this necessary repetition in a clear format. By isolating the regrouping skill, it allows educators to efficiently assess student mastery and provide targeted feedback, a practice consistent with findings on effective mathematics intervention.
