Meet the Grooved Pitcher & Glass, a Montessori classic we’ve perfected. Transferring a small amount of water back and forth between containers is a lesson in the properties of liquid. As your child pours, they discover the speed at which the water flows and how it assumes the shape of a container—or a surface, when it spills. 🙃@theparrishcrew #lovevery #learnthroughplay #montessori #childdevelopment #childhacks
