Approximation and Estimation
Students will round numbers to a specified number of decimal places or significant figures and estimate answers to calculations.
Key Questions
- Justify when it is appropriate to use estimation rather than exact calculation.
- Analyze the impact of rounding errors in multi-step calculations.
- Differentiate between rounding to decimal places and significant figures.

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.
