High School OER Math Suggestions

[Maria Beteran]

Hello everyone, 

I am currently seeking Open Educational Resources books in Geometry and Statistics for our school. Our teachers are interested in reviewing available options that would benefit our high school students. 

Any suggestions would be greatly appreciated.

Thank you, 

Maria Beteran

For Statistics, we use:

https://spot.pcc.edu/math/ahss/ed2/frontmatter.html

This is a PreTeXt conversion of one of the OER books released by OpenIntro:

https://www.openintro.org/

They have several closely related statistics books, but only release them as LaTeX PDF.

You are probably aware of OpenStax's statistics book. We tried it for a short while and the reports from our faculty were that they preferred OpenIntro. But the OpenStax book is probably used widely.

Hi, I have an OER in statistics equivalent to an AP level statistics class. http://MostlyHarmlessStatistics.com

The website has two versions of the textbook. The Mostly Harmless Elementary Statistics is the newer version and does not contain as many topics as the Mostly Harmless Statistics texts to align better to the new common course STAT 243z course.
