🧭 Teacher Notes, Success Criteria & Supports

Success Criteria

- I can test whether two ratios are equivalent by simplifying or scaling.

- I can find the missing value in a ratio using multiplication or division.

- I can apply equivalent ratios to solve real-world problems (e.g., recipes, rates).

Differentiation Strategies

- Struggling learners: provide ratio tables or scale factor cards and one-on-one guided examples.

- On-level learners: use scaffolded prompts and allow calculators for arithmetic checks.

- Advanced learners: give ratio puzzles with three-term chains or require proof using factors.

Extension Activities

- Create a real-world scaling task (map scale, mixing paint, or converting a recipe) and show equivalent ratios used.

- Challenge: combine ratios to solve multi-step proportional problems (e.g., unit rates then scale up).

Dyslexia-Friendly Reading Options

- Provide printed copies with increased font size and wider spacing.

- Offer colored overlays or high-contrast paper and short, simple sentences for each question.

- Allow text-to-speech/read-aloud and extra time for reading and processing.
