More on person-days

So today we took more notes on this whole person-day thing. Here we go:

If you are given people and days, multiply to find person-days.

If you are given person-days, and people (or days), divide to find days (or people)

If you are given people and days, and asked to find people and days, you must first multiply to find person-days, and then divide to get your answer.

We practiced a bunch in class, so you should have no trouble (if you were listening).

Homework: Period 1 is a day behind, so they are doing p. 702 (2-20 even)
Period 2 is catching up, so they are doing p. 702 (2-20 even) AND creating and solving 2 person-day problems,
Periods 3, 5, and 6 have to create and solve three person-day problems.

Best of luck, my little chickadees.

Arrivederci!
