If we are honest, there are often older children who become restless – bored perhaps? – in our prepared environments. Now six (or soon they will be six), they are transitioning to the second plane of development. They are outgrowing (or have outgrown) the design of the materials for the first plane – congruence and similarity. They are tiring of (or are already tired of) matching and sorting. Now they seek challenging learning experiences that involve equivalence. This presentation introduces experiences with equivalence found in project-based learning. PBL involves students with investigating a topic or question that interests them and creating a real-world product – a project – that represents what they have learned about the topic or that answers their questions. As children make their projects, they develop their abilities and skills to communicate, collaborate, plan their projects, make their projects, create solutions to problems that occur, and present their completed projects. During this presentation, Paul will describe equivalence learning, define PBL, and discuss how to organize and include PBL in our Montessori prepared environments. Children will no longer be restless!
