Wouldn't these be a lovely addition to your science area, and a beautifuly crafted compliment to the Parts of a Leaf puzzles! I just think that fall is THE best time to study leaves, with so many opportunities to extend the lesson outdoors collecting all those beautiful colors, leaf rubbings, leaf printing, and the list goes on...!!!!
This set was found on Etsy at The Whimsy Tree's Etsy shop. Please see their store for more sets, including natural log building blocks, and animal track matching game.
And as an added bonus, no toxic paint or plastic pieces to worry about! Piece of mind is priceless.
