Axial Symmetry and Reflection on a Coordinate Plane
Performing reflections of 2D shapes across the x-axis, y-axis, and other lines on a coordinate plane.
Key Questions
- How do the coordinates of a point change when reflected across the x-axis or y-axis?
- Predict the image of a shape after a reflection across a given line.
- Analyze the properties of a shape that are preserved or changed after a reflection.

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.
