What's Inside

This four-page PDF resource includes a full answer key. The worksheet contains four parts: a two-digit addition warm-up, a three-digit challenge, real-world word problems, and a "Missing Digit Detective" activity. This variety keeps students engaged while reinforcing the core skill from multiple angles.

Skill Progression

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

• Guided Practice: It begins with 8 problems focused on 2-digit addition to activate prior knowledge and build confidence.
• Supported Practice: Students then apply the same place-value strategies to 12 three-digit problems and 3 contextual word problems.
• Independent Practice: The final 4 "Missing Digit" problems require students to work backwards, providing a true test of their conceptual understanding.

This structure ensures every learner can build mastery at a steady pace.

Standards Alignment

This worksheet is aligned with Common Core standard CCSS.MATH.CONTENT.2.NBT.B.5: Fluently add and subtract within 100 using strategies based on place value. It also serves as a foundational step toward Grade 3 standard CCSS.MATH.CONTENT.3.NBT.A.2 (adding within 1000). Both standard codes can be copied directly into lesson plans, IEP goals, or district curriculum mapping tools.

How to Use It

Use this resource for independent practice after a lesson on place value and addition. Students can typically complete it in 20-30 minutes. Alternatively, use the final section as a quick exit ticket to assess understanding. While students work, circulate and observe how they set up the word problems to gain insight into their thinking process.

Who It's For

This worksheet is for 2nd and 3rd-grade students learning multi-digit addition without regrouping. It’s ideal for general education, resource rooms, or homework support. While not leveled, teachers can assign specific sections based on student readiness. Pair this with a place value anchor chart to provide visual support for students who need it.

This worksheet provides targeted practice for CCSS.MATH.CONTENT.2.NBT.B.5, helping students fluently add multi-digit numbers using place value strategies without regrouping. Its design reflects the gradual release of responsibility model, a proven routine for building student independence. As described by Fisher & Frey (2014), moving learners from guided warm-ups to more complex, independent tasks ensures they internalize both the procedure and the underlying mathematical concepts. The progression from 2-digit to 3-digit problems and word puzzles provides the structured repetition needed for fluency. By focusing on this foundational skill without the cognitive load of regrouping, this resource helps students build a solid base for more advanced arithmetic.
