This teacher’s guide provides the background information, STEM concepts, and strategies needed to successfully implement an early STEM curriculum (Ramps and Pathways) with young children, ages 3–8. R&P actively engages young children in designing and building ramp structures using wooden cove molding, releasing marbles on the structures, and observing what happens. Children use logical-mathematical thinking and problem-solving skills as they explore science concepts related to motion, force, and energy. This one-of-a-kind resource uses a newly created Inquiry Teaching Model (ITM) as the conceptual framework and devotes specific attention to the importance of an inclusive, social, STEM learning environment in which children are free to collaborate, take risks, and investigate within the context of exploratory and constructive play.
