Enlargements (Negative Scale Factors)
Students will perform and describe enlargements using negative scale factors, understanding the inversion effect.
Key Questions
- How does a negative scale factor change the orientation and position of a shape?
- Explain the significance of the center of enlargement when using a negative scale factor.
- Predict the coordinates of an image after an enlargement with a negative scale factor.

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.
