Warm Up
Thursday, Feb 21st last block (block G) some of you will have the opportunity to show what level of math 10 you have achieved this year. This is a math competition called the Cayley. It is 25 questions where you are simply seeing how well you can problem solve. For those participating you will need a permission slip, you need to bring a pencil and calculator and I will be considering this as evidence of math reasoning. Let me know if you are willing to give it a try. Here is last year's competition Cayley 2012 and the key.
Today we will be looking at this equation (to your left)...but first lets do a quick warm up. Visit the graphing stories web site, watch one or two situations and complete the sketch and analysis on last day's graphing stories handout. When finished work on your quiz corrections and/or complete assignment #4 - slope.
Lesson
Today we will first take a look at a very useful form of the equation of a line. First let's take a look at the app: "quick graph pro"

Familiarize yourself with the quick graph pro app. Try typing in a variety of equations. For example which polynomial functions are lines? (recall a polynomial equation has whole number powers, so a polynomial functions is in the form y = p(x), where p(x) is some polynomials. Try zooming in and out, then hold your finger on the graph to see co-ordinates on the graph (that you can move around) as well as the x-intercepts or zeros.
Now that your are familiar with the app, turn to page 355 and begin working through the math lab. You may work with a partner but you each must complete the work on your own. Once this is complete we will begin today's practice (which will be from lesson #6 NOT #5). We will be skipping over lesson #5 at this time and likely until after the break.
Wrap Up
Be prepared to share what you learned today on a socrative ticket out the door.
