**Why do we estimate a quotient?**• Sometimes an exact answer isn’t needed. • Six friends collected a total of 262 box tops. Each collected about the same amount. About how many box tops did each collect?**When we do need an exact answer, estimating the quotient**always helps us know if our exact answer is reasonable.**There are 262 students scheduled to be in PE at the same**time. The coach plans to teach a new game. Each group of six players will need one volleyball. How many volleyballs does the coach need so that every group has one? • Which would be a better estimate: 20 volleyballs or 40 volleyballs? • Does the coach need an exact answer?**Estimation Strategies**• Rounding • Compatible Numbers**Rounding**• Round 262 to 300. 300 ÷ 6 = 50 50 volleyballs is an overestimate since 262 was rounded to 300.**Compatible Numbers**• Substitute 240 for 262 because 24 is a multiple of 6. 240 ÷ 6 = 40 40 volleyballs is an underestimate since 262 was changed to 240.
