1. GRADE BAND: HS GEOMETRY Domain: Modeling With Geometry

2. Why this domain is a priority for professional development  Real world applications  Modeling in high school is going to be a big stretch for high school teachers  Modeling is motivational for students, not just in geometry but throughout high school  Many employers will be looking for this type of skill

3. Key standards in this domain that pd should focus on  The cluster “Apply geometric concepts in modeling situations” provides good examples for introducing teachers to modeling in general.  Fermi problems (do all the birthday cakes eaten in a year fit into the University of Phoenix Stadium) introduce teachers to important aspects of modeling such as making reasonable assumptions and estimating.  Solving geometric design problems involves making strategic choices about the simplicity versus complexity of the model (easier here than with algebra and functions).
