In this post, I share a video that walks you through my method for teaching students how to graph secant and cosecant functions. If you're struggling to find an effective technique for teaching your students this topic, keep reading!

⁠In this post, I share a video where I walk you through my method for teaching students how to graph tangent and cotangent functions.

In the summer of 2023, I presented at the Summer Math Summit (a Virtual Conference for Math Teachers).  My topic was "Tips and Strategies for Teaching Precalculus."

Ever struggled with writing equations of exponential functions?

Here's a way to generate the sum and difference identities for sine and cosine! Fun fact: I sped up the video so my voice sounds higher than it is in real life. 😀 You may be interested in my Sum and Difference Identities Circuit .

There are lots of websites that make it easy for teachers to create review activities for their high school math classes (quizlet, kahoot, etc).  But sometimes the internet goes out, or several of your students forgot their devices, or the batteries on their devices died, or the device won't connect to the interne…

I recently learned of a new review game that I am excited to play with my students. It's called Bluff.

When I was a kid I loved doing puzzles or hunting for Easter Eggs or solving math problems! Doing a Scavenger Hunt Review Activity is like the best of all of those things!

Trashketball is a fairly well-known math review game. You may have already played it. Maybe you played it when you were a high school student!

You might work in a state or country where there are Precalculus standards that you have to cover, you might work in a state where the standards only cover up to Algebra 2, or you might work in a private school where you have more autonomy about what to teach in Precalculus. If you are one of the latter two cases, the…

If you're looking for a math project idea for your high school students, keep reading. By far, the most exciting thing I do in my high school math classes is to give my students my How to Adult Project . Students select a profession with a salary and monthly student loan payment out of a hat. Working with a partn…

"DeltaMath is the bomb dot com." That is what I said to a former colleague when he admitted to having never used DeltaMath.com. He and I have been teaching high school math for over 20 years (which you could probably guess by my use of the very trendy "dot com" joke).

Today we played a Raffle Ticket Review Game in my Precalculus class. It was a huge success. The students were the most excited about doing math than I have ever seen. That may be because the semester is almost over (we are reviewing for the semester exam) or it may be because I haven't had them do many activities …

I think we math teachers can all agree that in some ways teaching math is easier than teaching other subjects. We don't have to grade essays, for example. Our grading is a lot less subjective and generally takes less time than our peers' in the humanities departments.

I call it Group Board Work. In 2017 I went to a teaching conference: Twitter Math Camp (TMC). (They haven't had one since 2018, and I don't know if they will have one again, but it was an awesome conference.)
