PreTeXt.Plus | Writing Accessible Course Materials with PreTeXt: workshops in July & August 2026 | Office Hours at MAA MathFest
To help our colleagues adopt PreTeXt to meet this need (whether via the PreTeXt.Plus app, or a local install of PreTeXt's free and open source software), we're excited to offer several virtual workshops this July and August.

#PreTeXtGang win during the Canvas outage: I had been embedding worksheets and annotated notes in Canvas (Thanks @oscarlevin.com !) from GitHub-pages deployed stuff. Just had to email students direct links to the entire thing. Quickly built and deployed exam questions that had been posted as SCORM.
