Adding Multi-Digit Numbers with Regrouping
Students apply place value understanding to fluently add multi-digit whole numbers using standard algorithms and visual models.
Key Questions
- Analyze how regrouping in addition relates to place value.
- Construct a step-by-step explanation of the standard algorithm for addition.
- Predict the sum of two multi-digit numbers using estimation before calculating.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
