Geometric Transformations: Enlargement
Students will perform and describe enlargements of shapes from a center of enlargement with a given scale factor.
Key Questions
- Analyze how the scale factor and center of enlargement affect the size and position of the image.
- Differentiate between positive and negative scale factors in terms of their effect on the image.
- Construct an enlargement of a shape given a center and a scale factor, including fractional scale factors.

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.
