What This Standard Means
What Students Need to Do
- Students compare the full cost and terms of purchases, subscriptions, and payment options. They check reviews, fees, and requests for personal data before deciding how to buy.
What Mastery Looks Like
- Given two checkout pages, a student can calculate the total cost and spot an automatic renewal. They can explain which option fits a budget and name a warning sign in a review or payment link.
Common Misconceptions
- Students may treat the listed price as the final cost or assume a free trial ends on its own. They may trust high star ratings without reading reviews or overlook fees on small installment payments.
How to Assess It
- Exit ticket: Cart A costs $28 plus $7 shipping; Cart B costs $32 and includes a trial that renews at $9 monthly. Which would you choose, and what must you check before paying?

Ways to Teach It
Give pairs two printed checkout pages; have them circle shipping, taxes, and renewal terms before choosing a purchase.
Ask: Would you give a shopping app your location for a 10% discount? Write two sentences explaining the tradeoff.
Play payment-card sort: students match four purchase scenarios to debit, credit, or buy now, pay later, then flag any fees.
Use two local grocery flyers to calculate cereal unit prices and pick the better buy for a weekly shopping list.
