180 – Day 60

Test day for Calculus. Implicit Diff, Chain Rule, Related Rates. It is the logical thing to do, test before Thanksgiving Break, but there were a number of students absent. They’ll have to do the make up after break, but I am not sure how well that is going to go for some.

I was a little ambitious in Honors Precalculus. My goal for today was to introduce students to Conics in Polar Form. I first wanted students to determine what cosine and sine did to the graphs of polars with this exploration:

Students worked well on this, but it took much longer than expected, I think because the holiday weekend was almost here. So we ended up going through these notes a little fast. Again, there were a few absent students, so doing a refresher problem or two after Thanksgiving Break may not be a bad idea. Of course, my goal is exposure to the topic, in case their future math classes use conics and parametrics, they would have at least heard of this.

180 – Day 59

Did I mention how much I love Desmos?! This site has been making my conic section notes soooo much easier! And they mean so much more to the students since they can actually see what is going on with the graphs.

I also assigned my students a graphing project using Desmos. They are free to do the project by hand, like my students have in the past, but I suggested they utilize the online graphing calculator to make this more interesting, and to keep the focus on the math, versus the drawing! I am interested to see what my students come up with. Here is a link to the project, if you’re interested.

180 – Day 53

How do we get so busy?! I don’t think there are enough hours in the day! It was 2nd derivatives implicitly today. I had a lot of students absent in calculus (senior class) due to the junior/senior day of Real Talk and a trip to Nationals for our marching band. It’s great that my students are doing so many fantastic things, but it’s hard on a class when there are a lot of students missing!

We were busy in Honors Precalculus, still working with conic sections. Notes on hyperbolas, and some trickier ellipse and circle problems. This group can and did handle the challenge.

180 – Day 50

I was out today. I went to my county ISD for a PD session on Formative Assessment. It was interesting, but since finding The Global Math Department, leading me to tweeps and the MTBoS, formal PD seems to be lacking something. But it was still informative, and left me with a lesson to try with my class.

While I was out, I left my Honors Precalculus class a notes sheet on ellipses.

This should be review for them, though they have not worked with them in a while. I love that Desmos does conic sections so easily! It makes my notes look so much better! We shall see how they did with this tomorrow!
