Diagonals in Rectangles
2024 marks the 10th anniversary of CAMI (!) and to honor all we have learned and all the ways we have grown as a group, we are going into the vaults for a few CAMI meeting, to reopen and revisit some of our early explorations together. This month’s meeting was a new take on a problem we explored in June 2016 at Making and Testing Conjectures: The Diagonal Problem.
We started with a Which One Doesn’t Belong?
Function Diagrams
I decided to lead a meeting on function diagrams because I’m intrigued by the possibilities of teaching with them and because I wanted to introduce the resources that the math educator Henri Picciotto makes available. I have to admit that I haven’t spent that much time thinking about to teach with function diagrams, but I was interested to see what we can learn together by exploring this visualization.

During our Tuesday, April 18th CAMI meeting, Gina Cortez and Amy Vickers facilitated a conversation around shadows.
Notice/Wonder
We showed this slide and asked the group what they noticed and wondered.
Billiards!
Today we looked at a problem involving rebounding balls on a billiard table.
The rules of our problem:
- A “table” can have different dimensions (measurements of height and width).
- A “ball,” modeled by a straight line, is launched at 45 degrees from the bottom left corner of a table.
MoMath Area and Perimeter Puzzle
Cindy started the meeting by asking participants to draw rectangles in Jamboard using the graph paper background.
Tip: To make a straight line in Jamboard, hold down the shift key!
Stubborn as a Goat
For the May afternoon CAMI meeting, we considered the case of the tethered goat. We observed goats tethered to fences and barns of various shapes and sizes and considered the grazing area of the goats under various conditions.

Whole Group
We started this meeting with a Which One Doesn’t Belong which also included talking about what the four pictures have in common:
Star Polygons!
In April’s evening CAMI meeting, Audrey led us through an exploration of star polygons…at a safe distance.
Math Art Challenges
Annie Perkins is a middle school/high school math teacher in Minneapolis, MN and she has been sharing a daily math art challenge every day since the governor’s made the call for everyone to stay at home. As I write this, we are going on Day 19.
