Foci of Parabolas Exploration

You have to love the Internet and the inspiration you get from other teachers. I put together an investigation based on the tweet below.   Inspired by a session at #T3IC last year, we used lasers to find "mystery points" (foci) of parabolas based on their lines of reflection. The conversations turned to satellites, flashlights, [...]

Marginless Domain and Range Cards

I was intrigued by Sarah Carter's Domain and Range Cards on her Math=Love blog. I was afraid I would lose a lot of time having my students cut out the cards, so I made border-less cards with functions my Pre-Calculus students will see throughout the year. Pages 1 and 2 are the framework for the [...]

Below are [...]

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 [...]

Sine, Cosine, and Tangent Ratios

Spring break brought out the creative juices. I spent time reworking guided notes sheets from last year into doodle notes this year. I like how they turned out. The Tangent Ratio Sine and Cosine Ratios I love it when I can start the class with a real world problem and help them arrive at a [...]
