## Polar Cards

Cindy Johnson’s Conic Cards are the inspiration behind Polar Cards. How she took the time to create 8 decks of conic cards is beyond me, but my students loved and learned from them. In my classroom, my students first perform a Polar Graphs Investigation. This helps them explore the graphs of the polar equations they [...]

## Polar Coordinates and Graphs

I remember being frightened by the polar coordinate system and graphing equations using it when I was in my students' seats many years ago. With graphing calculators, this doesn't have to be intimidating. I started the unit with an introduction to the polar coordinate system and reminded my students about how intimately familiar they are [...]

## Conics!

It's conic section time in Pre-Calculus. Learning from last year, I added a section on circles. I polled my students prior to spring break and they didn't recall the equation of a circle in standard form. To dust off the rust and get into completing the square mode, I created some Vizual Notes and a [...]

## Graphing Polar Equations

We have spent some time learning how to graph circles, limacons, rose curves, and lemniscates on the polar coordinate plane. The material you see below is borrowed heavily from Yosh's Graphing Polar Equations part 1, part 2, and part 3. I have included a link to the Word document instead of a pdf of the [...]

## Chords, Secants and Tangents, Oh my!

When starting a new unit on circles, I'm cognizant of how important learning the vocabulary is. Most geometry students are only familiar with the center, radius and diameter of a circle. Following a trigonometry unit, the word tangent takes on  a new meaning. The following notes sheets and study guides should help address this. Lines & Segments that [...]
