One concept that calculus students struggle with is volumes of solids with known cross sections. These three-dimensional solids, formed by slicing a region along specific planes, often leave our students bewildered. In this blog post, I will share several free and user-friendly websites that can aid both teachers and …

Visualizing the volume of a solid of revolution can pose a significant challenge for calculus students. In this blog post, I will share several free and user-friendly websites and programs that can help students visualize the 3D solids created.

When you're jazzing up calculus lessons on volumes of revolution, ditch the old-school board sketches!

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!

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.

Suppose you have been assigned to teach a course called Honors Calculus, Applied Calculus, Dual Enrollment Calculus, College Prep Calculus, Principles of Calculus, Introduction to Calculus, College Calculus, Fundamentals of Calculus, or just Calculus. In that case, you're in the right place!

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.)

How I got the idea for the game I was looking for some math review game ideas and I came across an elementary teacher's blog where she discussed a review game called Stinky Feet. She calls the game Stinky Feet because she allows the winning team to take their shoes off for the rest of the day. That's not goin…
