Last fall my 6–9s ground red ochre with river stones and painted with walnut ink; now I’m hunting for continuing ed that centers child-led process with natural materials. Have you taken a course (ideally 10–15 hours, CEUs) on plant pigments or eco-printing that felt aligned with Montessori?
I’ve had good luck with NAEA’s Professional Learning Studio — search “natural dye” and “eco-printing,” build a 10–15‑hour playlist, and they’ll issue CEU certificates: https://www.arteducators.org/. It’s not Montessori-branded, but the child-led exploration translates cleanly (letting the plants do the teaching). Do you need online only or would an in-person weekend work?
Piggybacking on @amelia46, The Art of Education University’s PRO Learning lets you build a 10–15‑hour track on plant inks/eco‑printing and they’ll issue PD certificates many states accept — just double‑check your CEU rules: PRO Learning - The Art of Education. Want me to share the specific packs that mapped well to 6–9 practical life and art?
