As of 12:50ish we had a 25% chance Thursday and a 19% chance Friday with a note that this was likely an early dismissal. Both are in the slim to none range so DO YOUR HOMEWORK and GO TO BED ON TIME just in case. A snow day is better when you are rested and don't have homework anway.

Notes

13.1 problem 1 clarification on the table.  Notice that we need the totals on the second column, not the number of dams and the number of sires separately. It makes the pattern make more sense. 

13.1 Problem 2: This is all of the information you need to completely answer the question.

The parentheses confused several people so we worked some problem to help with the difference in parentheses and negative sign position.  

A few more examples for 13.1 problem 2

Use #3 to answer #5 and #6.

How do I rotate a shape?

Try turning the paper.

Or create an angle for each point.

This is a VERY detailed video that talks about how to use the protractor and everything.

These are rotations around the center, not a point on the shape but if you are having trouble seeing what the shape should look like at the end it helps.

How do I use the protractor to draw an angle?

Try this for practice.

You didn't give me a protractor.

Sorry, print this one.
