I do not know what to write about to benefit the class mathematically so here are some random funny things because humour is beneficial in its own special way.

That is a true mental breakdown.(
I couldn't get the picture to appear clearer)

And now some jokes.
Teacher: What is 2k + k? Student: 3000!
Q: What do you get if you divide the cirucmference of a jack-o-lantern by its diameter? A: Pumpkin Pi!
Q: Why do you rarely find mathematicians spending time at the beach? A: Because they have sine and cosine to get a tan and don't need the sun!
Q: Why do mathematicians, after a dinner at a Chinese restaurant, always insist on taking the leftovers home? A: Because they know the Chinese remainder theorem!
Teacher: "Who can tell me what 7 times 6 is?" Student: "It's 42!" Teacher: "Very good! - And who can tell me what 6 times 7 is?" Same student: "It's 24!"
A math student is pestered by a classmate who wants to copy his homework assignment. The student hesitates, not only because he thinks it's wrong, but also because he doesn't want to be sanctioned for aiding and abetting. His classmate calms him down: "Nobody will be able to trace my homework to you: I'll be changing the names of all the constants and variables: a to b, x to y, and so on." Not quite convinced, but eager to be left alone, the student hands his completed assignment to the classmate for copying. After the deadline, the student asks: "Did you really change the names of all the variables?" "Sure!" the classmate replies. "When you called a function f, I called it g; when you called a variable x, I renamed it to y; and when you were writing about the log of x+1, I called it the timber of x+1..."
Q: What is the most erotic number? A: 2110593! Q: Why? A: When 2 are 1 and don't pay at10tion, they'll know within 5 weeks whether or not, after 9 months, they'll be 3...
Trigonometry for farmers: swine and coswine...
Q: How does a mathematician induce good behavior in her children? A: `I've told you n times, I've told you n+1 times...'
And finally for gregs benefit, the rock lobster video.
After the notes we went through some examples.
We were assigned exercise #47, questions 1-9. 
http://www.cartoonstock.com/
This is our assingment.
We then did some examples.
Using graphmatica we graphed the funtions y=x-2 and y=-x+2. Then we graphed the absolute value of y=x-2 and only the values above the x axis show. So basically each line below the x axis is reflected on the x axis and the part above the x axis is the graph.
The above example shows that this works.
To do these functions without technology we first draw the non-absolute funtion. Next we reflect only the portion below the x axis across the x axis. (as stated above.) We confirmed this with graphmatica.
Some more examples are shown above.
He also gave us some questions to practice with in the Mickelson book.Pg 12-35 Open ended set(show all work) and a multiple choice set.
