Accessible learning

The site uses semantic headings, labeled quiz controls, visible keyboard focus, a skip link, responsive layouts, and text explanations. Content remains readable without JavaScript; interactive quiz scoring requires it.

Ways to use the site

• Navigate links and controls using Tab and Shift+Tab.
• Use browser zoom to enlarge text.
• Open lesson answer disclosures with Enter or Space.
• Print lesson pages for offline work.

Known limits

This release has not received an independent accessibility audit or testing with every assistive technology. If an activity is difficult to access, an educator can provide an equivalent oral or written version.
