For teachers

Free classroom packs of true stories, experiments and puzzles, each with a starter question, a discussion prompt and its original source. Project them or print them, no sign-up needed.

Every card credits the book, paper or primary source it comes from, so students can follow up. Packs work full-screen on a classroom projector and print cleanly as handouts.
