Fun Pythagorean Theorem Activities and Teaching Ideas

Are you teaching the Pythagorean Theorem and looking for fun lesson and activity ideas? This post rounds up some fun Pythagorean Theorem activities and teaching ideas, including a wordless proof and worksheets that will engage all learners. Students in 8th grade math and geometry will love the hands-on and interactive ideas in this post. Included games, lesson ideas, worksheets, notes, independent work, activities that make for great centers and stations and a lot more.

This is a bit embarrassing, but because I try my best to swallow my pride and embrace growth mindset, I'm fessing up. It was during my first year teaching that I finally realized what a2 + b2 = c2 really meant. 


My friends and I collaborated on this list of fun Pythagorean Theorem activities and teaching ideas to engage all of your students. Included in this post are links to  Pythagorean Theorem games, puzzles, math pennants, coloring activities for word problems, math word walls, task cards, notes and even a way to make proving the Pythagorean Theorem fun!

To be fair, I was a biology teacher teaching algebra and hadn't seen the inside of a geometry book since high school. Geometry students' Pythagorean Theorem projects were hanging on a bulletin board in the hall and when I stopped to look at them, suddenly it all became clear. 

Pythagorean Theorem water proof

If only there had been GIFs when I was in high school!

Back in 2004 Teachergram wasn't yet a thing. If it was, I'm sure things would have been different. These days with social media, the ideas are constantly flying, making us all better teachers. And learners!

Through social media, blogging and TpT, I've also made some good math teacher friends (who I lovingly refer to as my "math friends") and in this post I want to share some of their fun Pythagorean Theorem activities.

Pythagorean Theorem discovery worksheet

If proving the Pythagorean Theorem had been a thing when I was in 8th grade math, maybe my first year of teaching wouldn't have been so... eye-opening. Amanda from Free to Discover made this Pythagorean Theorem Proof Discovery Worksheet to prove the theorem.

Pythagorean Theorem bookmark notes

Kara from Learning Made Radical has been making these great math bookmark notes that I can just imagine kids referring to late at night while doing homework. She made this set of Pythagorean Theorem Bookmark Notes

Pythagorean Theorem math pennant activity

It's hard for me to believe that I've made over 100 math pennants

Of all of them, this Pythagorean Theorem Math Pennant was one of the most difficult to make because of all of the graphics. Students find missing side lengths of the inner right triangles, areas and perimeters. 

Pythagorean Theorem partner scavenger hunt

Kara from Learning Made Radial and I have been collaborating on partner scavenger hunt activities that get students working together on their math. 

I had a senior a few years ago who had a boyfriend who she never spoke to face-to-face. This got me thinking about kids and how they need time during their day for meaningful conversation. Kara made this Pythagorean Theorem Partner Scavenger Hunt activity.

Pythagorean Theorem hole punch game

Kara also made this fun Pythagorean Theorem Hole Punch Game

Pythagorean Theorem word problems coloring worksheet

Karrie from Mrs. E Teaches Math made this Pythagorean Theorem Word Problem Coloring Sheet

Voyage to the Treasure! Pythagorean Theorem game

Alex from Middle School Math Man and I have been collaborating on a new math game series called Voyage to the Treasure!

Voyage to the Treasure! Pythagorean Theorem game

In these new math games, students are on the same team, working through math problems as they try to beat the Math Monster to the treasure. The one above is Voyage to the Treasure! Pythagorean Theorem.

Pythagorean Theorem puzzle activity

Mel from Secondary Math Shop made this Pythagorean Theorem Cut, Paste, Solve and Match puzzle where students set up and solve Pythagorean Theorem problems. 

Pythagorean Theorem color by number worksheet

Hayley from Activity After Math made this Pythagorean Theorem Color By Number activity where students find a missing leg, hypotenuse, converse or the distance between two points. 

Pythagorean Theorem task cards

Hayley also made this set of Pythagorean Theorem Task Cards with QR codes. 


Pythagorean Theorem scavenger hunt

I've always had a lot of success with scavenger hunts with my students. They really seem to enjoy them. Alex made this Pythagorean Theorem Scavenger Hunt for 8th grade math students.

Pythagorean Theorem proof without words activity

Karrie wrote a great post called The Pythagorean Theorem Without Words over on her blog. The image above from her post is Perigal's Puzzle. 

Karrie also pulled together a list of her favorite Pythagorean Theorem resources in her post 7 Ideas for Teaching the Pythagorean Theorem.


If you have Geometry students who speak Spanish, this wordless Pythagorean Theorem proof has some funny outtakes at the end! Actually, they're even funny if you don't speak Spanish. 

Pythagorean Theorem word  wall reference

Lastly, I made this Pythagorean Theorem math word wall reference so that students won't find themselves in my position at 28 years old! I usually do not duplicate references between math word walls, but I did add this one to both 8th Grade and Geometry.

I hope you are having a wonderful year!


Are you teaching the Pythagorean Theorem? This post is a round up of fun Pythagorean Theorem activities and teaching ideas. Students in 8th grade math and geometry will love the interactive ideas in this post. Included games, worksheets, notes, independent work, activities that make for great centers and stations and a lot more.
