Transformations: Reflection
Understanding and performing reflections (flips) of 2D shapes across a line of symmetry.
Key Questions
- Analyze how a reflection changes the orientation of a shape.
- Design a shape and its reflection across a given line.
- Compare the properties of a shape and its reflected image.

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.
