Periods 1, 2

p. 645 (17-24)

Please remember to write these problems vertically (up and down).

Period 2 was told to estimate an answer before doing the problem. That can be done mentally or on paper, but an answer must be present before exact calculations begin.

It would be good if Period 1 does the same, but I didn't ask for it so it won't be graded off if it doesn't happen.
