Reviews Lesson 7.6, Lesson 7.8. Reviews the arithmetic of Lesson 7.6 (the class T-shirt, the 60-shirt twist, the cookies, business or hobby) and Lesson 7.8 Day 2 (the drawstring tote bag: unit cost, price, margin, fixed cost, break-even rounded up, the three errors, and guess versus reason on the projection). Round 1 is a five-second check on the profit formula before Lesson 7.8; round 2 is the Numbers Clinic warm-up at the start of Lesson 7.10 Day 1 in the one-period version, or the do now of Lesson 7.8 Day 2. Every number is from the handouts and the teacher key, so a student who misses sees the same sentence the teacher would say. Grade 6 plays round 1 only, which uses the same numbers as the ten-shirt version in the key. Calculators are allowed.
