It will be a few years before we get to celebrate the next Pythagorean Theorem Day in July of 2025. Here are some ideas for celebrating this fun mathematical holiday. For many, the Pythagorean theorem (also known as Pythagoras’ theorem) is one of the most memorable formulas from high school math. Most adults would likely …

Looking for a challenge? Check out this page of Make It Pythagorean Puzzles. Insert the same digit (in any manner of your choosing) to each side of the triangle to form a right triangle. I ran across these interesting puzzles in Golf on the Moon by Dick Hess (Dover Publications).

I want to share a pythagorean theorem poster I created several years ago for my classroom when I was teaching trigonometry. I designed this poster to print on 11 x 17 cardstock. I hung this poster on a bulletin board in my classroom with several other 11 x 17 posters I created. As I continue …

To give my students a bit more practice with word problems, I typed up these Romeo and Juliet themed pythagorean theorem problems. These are slightly modified from this Weebly site. Free Download of Romeo and Juliet Pythagorean Theorem Questions

I’m a rebel and chose not to teach the distance formula since it’s way easier to just use the Pythagorean Theorem instead. Instructions for Finding the Distance Between Any …

I created this set of free printable pythagorean triple posters to help decorate my new classroom. I’m teaching Algebra 1, Trig, and Math Concepts (a class for 9th graders not yet ready for Algebra 1) this year. As I was making a list of things my trig students need to review at the beginning …

I’m excited to share my student’s creative wheel of theodorus projects which I turned into a Wheel of Theodorus Bulletin Board to decorate my high school math classroom. Every year, I have this plan to change my bulletin boards out throughout the school year. This year that happened only once. It also happened way back …

These are the pythagorean theorem notes I used with my trigonometry students in our beginning of year geometry review. We glued these notes in our trigonometry interactive notebooks. The Pythagorean Theorem booklet was stole from the blog of Jessie Hester. She has a ton of resources for teaching the Pythagorean Theorem! If I was teaching …
