THURSDAY, DECEMBER 17TH Grab a green homework sheet and set of practice problems off the projector Any questions about last night s homework?
WINTER BREAK Mandatory Read and take notes on sections 19.5-19.7 Problem set 2 (similar to problem set 1 use it to refresh yourself before you get back!) Extra Credit Summative section of the gradebook up to 20 total points (10 per chapter, ~2% overall grade increase) Chapters 18 and 21 You can get partial credit See my website for details
