Solving Problems with Ratios and Scale
Students will apply ratio and scale factors to solve practical problems involving maps, models, and mixtures.
Key Questions
- Predict how changing a scale factor affects the dimensions of a scaled object.
- Construct a solution to a problem involving a mixture with a given ratio.
- Evaluate the accuracy of using a map's scale to determine real-world distances.

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.
