Dilations and Scale Factor
Students will perform and describe dilations of figures, understanding the role of the scale factor and center of dilation.
Key Questions
- Explain how a dilation changes the size but not the shape of a figure.
- Predict the effect of a scale factor greater than one versus less than one on the image.
- Analyze the relationship between the center of dilation and the corresponding points of the pre-image and 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.
