Cleaning a Leaf (ME021) is a practical life exercise that guides children through the careful process of wiping and polishing individual leaves on classroom plants, supporting fine motor refinement and purposeful hand movement in the 3–6 environment. The activity connects children to the care of living things, a core thread in Montessori's broader grace and courtesy and environmental stewardship curriculum. It pairs naturally with your plant care sequence and gives children a satisfying, repeatable task with a visible, concrete result.
