Reviews Lesson 1.16, Lesson 1.15. Reviews Lesson 1.16 (unit price, the better buy, the bulk trap, and the sales tax rule) in round 1 and the store sections from Lesson 1.15 in round 2.

Grade 8 stretch (comparing two circulars, tax to the penny) stays on the handout. Round 1 allows a calculator on the phone's other screen only if the teacher says so; the choices are close on purpose.
