## Trig Hexaflexagon

My honors precalculus students saw the slope hexaflexagons my geometry students were using and asked when they would get something like that. I promised when we reached our trig unit, I'd whip something up. Below is the result as well as a video explaining how to assemble a hexaflexagon. My hope is that my students [...]

## 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 [...]

## 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 [...]

## Combinations of Functions and Composite Functions

Composite functions are a combination of two functions. The traditional math course introduces them like this: Let f and g be functions with overlapping domains. Then for all x common to both domains: (f + g)(x) = f(x) + g(x) (f - g)(x) = f(x) - g(x) (fg)(x) = f(x) · g(x) (f/g)(x) = f(x) / [...]

## Graphical Symmetry

There are three types of graphical symmetry you may be responsible for: x-axis, y-axis, and origin. Knowing the properties of symmetry can help you when sketching complex graphs. x-Axis Symmetry If an equation or function is symmetric with respect to the x-axis. you can fold the paper it is graphed on along the x-Axis and [...]
