If you follow Montessori Journey, you will find that this is similar to her leaf post. Purely, coincidental we both added leaf rubbings to our classrooms yesterday!
A few weeks ago at a festival in our area, I found these glass leaf bowls at an antique store for 50 cents each. I bought 4 of them. 2 have dividers and 2 are open. The divided bowl is for sorting the leaves into attributes of their choosing. I read Red Leaf, Yellow Leaf to the class yesterday as an enticement for this work. The leaf book is teacher made for identifying the type of leaf. I have a sample leaf rubbing with a label for the type of leaf. In the pumpkin are crayons for the rubbings.
