Friday September 11th's class

Some students were struggling using these calculators. They could not find the “abs” or figure out how to graph these equations. Seeing that the focus of todays class was using these graphing calculators, we need further instruction on how to use the different utilities on these calculators. Some forgot how to graph palaboras, solve quadratics, and use domain and range. Solving quadratics to find the domain of equations was another struggle we had. Few kids can remember the equations such as point slope, distance formula, midpoint formula, and others. When in front of us we can use them, however remembering why they work (as you explained in class) is different. We should go over the definitions of intervals (relative minimum/relative maximums) and odd/even functions. Other than those things the class did not have many questions. None of these stuck out as a great problem other than using the calculators.

    Thanks for the post, Tyler.

    First of all, apologies! I'm having a little trouble keeping my Red/White days straight, and I thought I had already given you guys some instruction on the graphing calculators (GDC's). Of course, I hadn't! Next class, I will go over how to use the GDC a bit more slowly. Apologies.

    We haven't discussed even/odd functions yet, so we will next class. We will also discuss intervals of increasing/decreasing and relative extrema.

    Thanks again!

    Mr. Obrien,

    The scribe for next class will be none other than Nate the great.
