Holler at us.

Found a mistake? Want a lesson that isn't here yet? Using the library in a way we should hear about? Tell us.

Report a mistake

Accuracy matters more than anything else here. If you find a wrong answer, a factual error, a broken page, or wording that talks down to students, email us with:

  • the lesson code from the page footer (for example, HACK-01),
  • the page number, and
  • what's wrong and what you think it should say.

Fixes go out under the same code, so your shelf labels never change.

Suggest a lesson

Tell us the topic, the grade band, and what your students keep asking about. Lessons in the works include penmanship and cursive, more math, writing, reading, and biology hacks, career explorations, and overlooked history.
