Teacher Mode
Enter the teacher access code to turn on Teacher Mode across the site. Every content page that has a teacher guide then shows a Teacher Guide link just under its title, and a small “Teacher Mode on” pill sits in the bottom-right corner of every page with shortcuts to the guides and an Exit button.
The guides open right here on educs.me. The first time you open one, it asks for the same access code once more to unlock it (the answer keys are encrypted), then remembers it in that browser for a week. No separate account, and you never leave educs.me. You can also browse the full list at All teacher guides, which is public and lists every guide by topic.
Teacher Mode is on. Content pages that have a guide now show a "Teacher Guide" link under the title, or browse all teacher guides.
