Welcome to Lower Dots. Here you will find free tutorials for the blind on a variety of topics in math and other subjects.
If this is your first time here, we invite you to first learn about how to use this site, choose your prefered output format, and then explore our courses.
If you find a problem or have a suggestion, please contact us and let us know.
This project is made possible by the generous support of the Lighthouse for the Blind and Visually Impaired of San Francisco through their Holman Prize. We are deeply grateful for their many contributions.
What’s New
We are just getting started, so while there isn’t much here today, we are continually adding more. If you would like to help us grow the site through donations, volunteering, or otherwise, please contact us.
At the moment, our efforts are primarily focused on building out the Pre-Algebra course.
