Complete, Free Guide to Teaching Slope
In the inquiry activity, students have to work with a partner with almost no guidance from the teacher to decide how they will order the "steepness" of a variety of ramps and staircases from least steep to steepest.
This challenge will lead them to find a way to assign numerical values to the steepness and make observations from there. It's a perfect way to build the foundation for the concept behind slope.
Here's a peek at what's included. Click here to download the Slope Teaching Guide and get the printables and teaching tips. The only "catch" is that there are a few ads included for related slope resources! :) Enjoy!

8 Activities for Your Math Club
Keep These On Hand If You Are Moderator of Your School Math Club
Are you a newly appointed math club moderator? Or a pro looking for new tricks and activities?
I've been there, and realized that I wanted to start a collection of some of the activity ideas that would be great to share with the club when we have some time.
Here are some that I have created, discovered, or stumbled across online (ALL FREE!)
This way, we can have them all in one place for when we need to fill a full math club block or just a few minutes at the end or beginning of the meeting.
These are mainly for middle school and early high school students. Hopefully these groups of kids will already have an interest in math and be excited to jump in to some of these!
This is a fun mathematical "trick," which kids generally love, but the math behind it goes deeper. To figure out why it works, kids have to use their skills of:
- writing an expression to represent the problem
- combining like terms
Here is the trick/problem and explanation.
A fun exploration that's accessible to students of any age, mobius strips are neat to see and interesting to take one step further. All you need is paper, scissors, tape, and a pen/marker. You can show students my video or lead them through it on your own. Can anyone guess what will happen if they make the final cut at the end?
Even you might be surprised if you haven't done this before!
These are great because they include instructions and options for different levels of difficulty. Kids can play online. This is a nice way to finish up the meeting if you have time to kill, or get a little competition started between club members while you wait for a math tournament if your math team travels.

Pi Shape Puzzle
This is another fun challenge that works for younger students. It's a cut-up shape puzzle for building spatial & geometry skills, but the extra twist is that the pieces start by forming the symbol for pi, then must be shifted to form a square. This makes it perfect for the mathletes in your club!
Here is the link for the Pi Shape Puzzle.
This is one of the coolest things to explore with your math team. Be sure to leave a whole meeting period so you can dive deep.
This is a perfect mix of math history and a higher level look at the concepts behind place value and digits. It will challenge even your high schoolers to try to approach numeric systems with different bases.
This free hands-on exploration pack has everything you need.
Million Dollar Problem
Kids love to imagine large amounts of money, so this one is a great challenge to get them thinking about. Be sure to show the picture at the end so they can see how much ten million dollars in pennies actually looks like.
Here's the problem...
...and the pennies
This is a classic problem, but an excellent one for partner work. Have kids show how they worked through this scenario, and then share their different approaches with other teams. It's a perfect way to get them talking about their own models and strategies and comparing with how other pairs in the room reached the same conclusions.
Here is a wonderful setup for starting the handshake problem with your group.
This set of brain teasers is so nice, because they are printable, and there are tons of them. It makes it so easy to use one per meeting to kick off and get started. These are perfect brain warm-ups.
