Proportional relationships

Teacher guidance revised 2 November 2026. Student tasks retain their stated core edition. Use the matching current teacher guide linked here.

Start with the teacher orientation. Keep answers and unused later tasks with the teacher. Share only the selected student pages.

Existing per-one foundations

For prerequisite teaching, open Unit Rates: Find Per One or use the current collection package. In that package, the prerequisite materials are in the unit-rates-find-per-one folder, with teacher guides separate from student stages. Retain independent and later tasks for their named occasions. Earlier archived ZIPs have their own folder arrangements.
