We are updating our site!

  • 👉 Our single PDFs won’t be available for purchase at this time (they will show "sold out"), but you can still get our discounted bundles. Aiming to complete new website before end of 2025.

    (If you need us to resend a PDF you previously purchased - or if you need to get a single PDF - you can always email us at hello@furiousthink.com 😊)


Our favourite feedback ever:

  • "Your books are a light at the beginning of our day."

    - from a Grade 7 Ontario teacher

What's your age range? 🧐

  • Yeah, we get a lot of questions about age. The truth is - it depends. Our questions are open-ended. Generally, we gear to 9 to 14-ish-y. But there's tons for older youth (+ adults!) and younger kids, too.
