Life After preCalculus: SAGE and preCalculus
Last March, I was a guest speaker at LIMACON 2013. I spoke about using SAGE in preCalculus class instead of a Graphing Calculator. I will continue working on these SAGE worksheets for my EBay offerings.
BTW, my YouTube project next year will be to re-record my preCalculus 4R. The current playlist was based on my Math 4R preCalculus for Seniors using TI-83s. Next year I have Math 4R preCalculus for Juniors going to AP Calculus AB and Math 4H preCalculus for Juniors going to AP Calculus BC. I think I will redo the curriculum with SAGE instead of TI-83s and start with Chapter 12 Sequences and work backwards to Chpater 3 Rational Functions. That way I can introduce Python Lists early in the year. Also, the last topic before we get to Calculus with involve Limits when we talk about Vertical, Slant and Horizontal Asymptotes wrt Rational Functions! Also, I will do somewhere between a Quarter and a Semester of Caculus at the end of the year. In 4R-12 I used to cover only a Quarter's worth of Calculus. This year, in 4H we did a whole Semester of Calculus. I think next year's 4R-11 and 4H will be somewhere in between. I was told to combine these 2 preps as one since I've had 4 or 5 preps every year for years now. It will feel like a vacation next year!

Here's a handout from my LIMACON presentation:
Here's the preTests I'm working with:
I've also been invited to speak for T^3 at Molloy College in November!
Well, that's all folks! I hope you got something out of all the above.
