Complete every decision, then check the rate reasoning.
This pilot aligns only to uncovered Key Stage 3 records MAT-0284 and MAT-0286. It samples selected original percentage-change, original-value, simple-interest, speed, unit-price and density problems. It does not establish general financial fluency, reliable rate selection or independent transfer across unfamiliar compound-unit contexts. It does not complete the ratio, proportion and rates-of-change unit, provide a lesson sequence or satisfy an assessment.
