Subtracting Multi-Digit Whole Numbers
Students will fluently subtract multi-digit whole numbers using the standard algorithm.
Key Questions
- Explain the process of 'borrowing' or regrouping in subtraction and its effect on place values.
- Compare the standard subtraction algorithm with other methods, such as expanded form subtraction.
- Assess the accuracy of subtraction calculations using addition as an inverse operation.

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.
