Questions about the free lesson

Still wondering? Email [email protected] — a real person answers.

Is it really free?

Yes. Drop your email, we send the PDF. We’ll also add you to our homeschool newsletter — unsubscribe anytime, no questions.

What’s the difference between this and the box?

Same lesson, same age tracks, same parent guide. The Recipe Box ships you the supplies. The free PDF asks you to source them yourself (supply list included).

Can I share the PDF with my co-op?

Yes — share it with friends and your homeschool group. If you lead a co-op of 5+ families, ask us about the Co-op Leader Free Lesson Box (we’ll send you a physical one).

What’s in the PDF

One full lesson. Free. Yours in 30 seconds.
