Data Science

# Online Interactives:

Playing computer games creates a lot of data, which usually disappear when the game is over. But in Data Games, you learn to analyze data that are saved, learning math and data skills that help you win!

### Rich Tasks and Data Sets:

### (for virtual and in-person learning)

You Cubed Data Science Units - Jo Boaler

Task, data, and resources provided by TODOS at the 2019 CMC Conference.

This is a social justice lesson in which students investigate if there is bias in who the police/highway patrol pull-over.

Here are recent local data

Data sets related to science experiments (although having students do the experiments and create the data would be more ideal)

Probability

Probability can be really fun. After getting a sense of the basics and exploring various “games”, students can create their own games of chance, with a discussion about the odds of their games, who the game favors, etc. A discussion and exploration of the Monty Hall 3-door problem is fascinating and does not follow our typical logic. Mathematicians argue about this problem.
