🧭 Teacher Notes & Success Criteria

I can... statements:

- I can write ratios to compare two quantities.

- I can find equivalent ratios and simplify ratios.

- I can use ratios to solve real-world problems.

Success criteria:

- Students write ratios correctly in a:b form and as "a to b".

- Students simplify ratios using greatest common factors.

- Students set up proportional relationships to solve word problems.

Differentiation strategies:

- Support: Provide ratio tables and one-to-one counters for students needing concrete models.

- On-level: Practice with mixed numeric and word problems.

- Advanced: Ask students to solve missing-term ratio problems and scale recipes up/down.

Extension activity: Have students create two different real-world ratio problems (one scaling up, one scaling down) and swap with a partner to solve.

Dyslexia-friendly reading options:

- Use larger spacing, colored overlays, or high-contrast backgrounds when printing.

- Read text aloud and allow verbal responses or use line-by-line reading support.
