Perimeter and Area Relationships
Exploring the relationship between perimeter and area, including finding rectangles with the same perimeter and different areas or with the same area and different perimeters.
Key Questions
- Design multiple rectangles that have the same perimeter but different areas.
- Analyze why rectangles with the same area can have different perimeters.
- Justify how changing one dimension of a rectangle affects both its perimeter and area.

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.
