This lesson is based on the MTLT article, “Inquiry + Math Workshop Model = Success!” by Tutita M. Casa, Kathryn O'Connor, and Emma Dearborne. The lesson demonstrates the use of a workshop model that engages students in developing strategies to solve an authentic multiplication task.People are apt to complain about weather forecasts and their accuracy. This is your chance to do something about them - or at least to understand their accuracy. In this lesson, students will gather data and crunch numbers to find out whether the weather forecasters are doing their jobs. Read the story behind Forecast Accuracy here. Aluminum cans get thrown out and run over - flattened. And when they do they provide a vehicle for students to construct their understanding of some important aspects of volume and surface area. Read the story behind Flat Cans here. Tides are phenomenal forces at work on our watery planet every day and all the time. As they tune in to tides at stations of their own choosing students will develop conceptual understanding of how a rate may be represented as the slope of a graph. Read the story behind Tidal Math here. Leaves are everywhere and they're awesome. Let students gather up some of their own and use them in your classroom to develop a clearer understanding of reflection (line) symmetry. Read the story behind Leafy Math here. Could Becca Swanson, current women's deadlift record holder, lift that tree trunk? That depends on the volume and the density. In this investigation students gather some tree data and construct their understanding of the formula for the volume of a cylinder and the role that density plays in determining weight. Read the story behind Tree Trunk Math here. 3-5
This lesson is based on the MTLT article, “Supporting LGBTQ+ Students in K-12 Mathematics” by Brandie E. Waid. In this lesson, students identify lines of symmetry for various symbols, create line-symmetrical figures and examples and non examples of images that have lines of symmetry, and analyze and discuss similarities and differences between their identify and that of their classmates. 9-12
This lesson is based on the MTLT article, “Visualizing Complex Roots of a Quadratic Equation” by Thomas Edwards, S. Asli Özgün-Koca, and Kenneth Chelst. In this lesson students use various tools to discover the geometric relationship between complex roots of a quadratic equation and the graph of the associated quadratic function.
