Quadrilaterals

Several years of work are coming together nicely. Unfortunately, I still have tests to grade. There are so many properties for students to know and remember in the quadrilaterals unit of Geometry. I started by creating flash cards on three sheets of paper. Students had to write the property based on the "quadrilateral hieroglyphics" displayed [...]

Squares and Square Roots

I was thinking about a way to make square roots more visual for my students. With graph paper, I started sketching out the perfect squares and then played with numbers that form rectangles rather than squares. The video below shows the process. https://youtu.be/E4zlffv4zns Ideally, students would be introduced to this method in middle school [...]

Looking for Patterns (Arithmetic Sequences and Finite Differences)

I bought and read Jo Boaler's "What's Math Got To Do With It?" last summer. She really gave me food for thought regarding grouping by ability and gender differences. I also read "Mathematical Mindsets" this fall. As a high school math teacher, I set a goal to make my teaching more visual, delve into the [...]

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 [...]
