You have 2 minutes to do all of the following

1. You have 2 minutes to do all of the following Take out your homework packet and put it on the corner of your desk Take out your independent practice sheet from yesterday and put it on your desk next to your homework. Put all extra credit in the container that I show you Get your warm up out and date it 12/9/11

2. Warm-It Up Evaluate each expression for x = - 1/2 x + 2 2.x + 4 – 22 3.x– 8 4. 10x – 4 5.8x – 90 6.-50x - (-7)

3. Whiteboard RULES Pens on your desk until I tell you to pick them up and write Pens down when I say pens down ONLY do the math on the whiteboards There are 27 markers in my box- no one leaves class until I have collected all of my markers and there are 27 markers back in my box Breaking any of these rules will result in you losing your whiteboard for the day.
