Messin' with p5*js
In anticipation of using some version of processing js in a nonAP computer science class I will be teaching this summer, I am just tinkering with arrays this morning. I like how this turned out.
Columbus Math Teacher Circle
I was fortunate enough to attend the Columbus Math Teacher Circle yesterday and to share the game Borel as a way to introduce my favorite instructional arc for teaching probability ideas: Intuition, Simulation, Calculation.
The first problem we looked at was this:
Roll three 6sided dice and one 30sided dice. Will the difference between the maximum value and minimum value showing on the dice be greater than 15?
Pause for a moment and think about this problem. What does your gut tell you? Then roll these digital Polypad dice to get a feel.

My Google Data Analytics Capstone Project
What do you hope to take away from this capstone project?
I am hoping to show that I can do it, and maybe demonstrate a practical understanding of data dashboards so I can better serve the schools I am working with.
What is one important skill you think you’ll learn?
I think just brining it all together...R, Kaggle, Tableau...
Which skills do you most look forward to demonstrating?
Google Data Studio perhaps? But I have learned a few new google sheets tricks
What are some issues you might encounter?

More Heads or Tails?
Over the course of 100 or 1,000 or 10,000 flips, will there be more heads or more tails? And once one side of the coin takes the lead, do they relinquish it at some point?
I explored this with a simulation using Texas Instruments' Nspire CX CAS with Python.

Flip a coin 10, 100, 1000, and 10000 times. Question: More heads (positive) or tails (negative)? @T3Learns pic.twitter.com/TxVt0fvHTB
Heads in a row?
How many coin flips does it take to get N heads in a row? Here is a simulation in Texas Instruments' Nspire CX CAS with Python
