At the heart of this meeting was the following table, shared by math educator Howie Hua:
What do you notice? What patterns do you observe?

Elementary Cellular Automata
To launch our explorations we noticed and wondered about several images:
This is the first one:
What do you notice? What do you wonder?

To launch our explorations, we looked at these two graphs:
What do you see?: Attention & imagination in math
Sometimes CAMI meetings have a mind of their own. This one followed a direction we didn’t expect!
We started with a question about this image:
The catch? We wanted to spark our creativity by exploring the world of wrong answers.
What is the Area? WRONG ANSWERS ONLY

In this CAMI meeting, Aren and Mark brought some tools for us to explore colors and play around with one way that humans have developed to quantify colors.
To get things started, we played around with a color slider. https://adultnumeracynetwork.org/Color-Sliders
Our task was to:
- Create a color that is meaningful to you, or
- Find the color that describes how you feel right now, or
- Find your favorite color
Number Triangles
In this meeting, we started by looking at the following two images.
What Would I Think If I Didn’t Know?
For this meeting, Aren invited us to explore the weird and wonderful world of numbers between 0 and 1. We started with a notice/wonder on this set of equations (suggested by Eric):
Happy Numbers
For this month’s meeting, we returned to explore some numbers we first encountered in CAMI back in 2015 (Happy Numbers and the Melancoil).
After some community building, we started our exploration with a notice/wonder of this diagram.
Sarah’s Passing Drill
In another edition of revisiting problems from the CAMI vaults, at this month’s meeting we went back to further explore a number pattern we first looked at in January 2017 (Carl’s Basketball Problem).
We started off discussing WHAT IS SIMILAR? WHAT IS DIFFERENT? looking at these four expressions:
Sequences of Fractions
In this meeting, we deconstructed a problem from NCTM’s Mathematics Teacher: Learning & Teaching PK-12, using a few ideas from The Art of Problem Posing, by Stephen I. Brown and Marion I. Walter.
Here’s the original problem:
