What's Inside

This five-page PDF contains a master quiz broken into four distinct parts. It begins with ten problems on two-digit addition with regrouping, followed by ten problems on two-digit subtraction with regrouping. A challenge section then introduces six problems with three-digit numbers, and the quiz concludes with two multi-step word problems. A complete answer key is provided for all 28 tasks.

Evidence of Mastery

This quiz produces clear evidence of mastery for CCSS.MATH.CONTENT.2.NBT.B.5 and bridges to 3.NBT.A.2. Its sections allow for granular assessment: addition, subtraction, extension to larger numbers, and application. While no rubric is included, scores from each part help identify specific strengths or weaknesses, making it easy to enter performance data into gradebooks or for IEP progress monitoring.

Standards Alignment

This worksheet aligns to CCSS.MATH.CONTENT.2.NBT.B.5, which requires students to fluently add and subtract within 100 using place value strategies. The challenge problems also address CCSS.MATH.CONTENT.3.NBT.A.2 (adding and subtracting 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 worksheet as a summative assessment after a unit on regrouping (25-40 minutes) or as a pre-assessment for Grade 3. For formative data, observe if students are using drawings, a number line, or the standard algorithm during Part 1. This reveals their strategic flexibility and conceptual understanding before they move to pure computation.

Who It's For

Ideal for Grade 2 students learning regrouping or Grade 3 students needing review. The progression from two-digit to three-digit and word problems provides a gentle ramp. For students who struggle, pair this quiz with a base-ten block anchor chart. For advanced learners, challenge them to write their own word problem using a three-digit calculation.

This assessment provides a reliable measure of student proficiency in core arithmetic skills outlined in CCSS.MATH.CONTENT.2.NBT.B.5. Fluency with multi-digit addition and subtraction is a key predictor of later success in mathematics, particularly in algebra. As noted by research from RAND AIRS 2024, procedural fluency and conceptual understanding are intertwined; this worksheet addresses both by moving from straightforward computation to application in word problems. The inclusion of problems within 100 and extending to 1000 serves as a practical tool for teachers to track progress against grade-level expectations. By assessing a student's ability to fluently add and subtract using place value strategies, educators gather critical data for standards-based grading, targeted intervention groups, and reporting student growth on foundational number sense competencies essential for all future math learning.
