Math and science integration is critical in developing problem-based learning around real-world issues. Effective STEM-based lessons can start with natural math/science integration to discover more about the world around us. In this hands-on workshop, participants will participate in innovative activities that illustrate the science and math behind real-world ecology concepts such as carrying capacity in nature, natural resource use, and how humans are forever changing Earth’s landscape, habitats and biodiversity. Presented strategies include creating representational models with manipulatives, cooperative group problem-solving challenges, graphing and analysis, and role-playing simulations. The concepts and learner outcomes in these activities adhere to key Missouri Learning Standards for science and mathematics. Receive lessons in an electronic format.
