Rounding Numbers to the Nearest 10 and 100
Students will round whole numbers to the nearest ten or hundred and use rounding to estimate sums and differences.
Key Questions
- What are the rules for deciding whether to round a number up or down?
- How can rounding help you check whether an answer is reasonable?
- What are some everyday situations where we use rounded numbers instead of exact numbers?

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.
