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 [...]

Using Normal Distributions

A normal distribution is one type of probability distribution. It has a bell-shaped curve. Normal distributions are often used when calculating grades and curving them based on the standard deviation. The notes sheet below asks students to use what they know about the mean and standard deviation to fill out a normal distribution template for the [...]

The start of the second semester has me teaching both Algebra II and Pre-Calculus trigonometry simultaneously. My initial plan is to post material for both classes here. It it becomes confusing or too cumbersome, I'll split the two classes. Algebra II Right Triangle Trigonometry A foldable on trig concepts seems in order given the amount [...]

Exploring Inverses of Functions with Desmos

Learning through discovery is always better than being told something - unless it involves something that causes pain. I learned about electricity when I was 4 years old by sticking a key into an electrical outlet. I had been told not to, but the lesson didn't sink in until I tried it on my own. [...]
