Insights for Teaching High School Geometry
- Many Web sites that are unattractive or hard to navigate are full of good, free educational resources. Although findingDulcinea usually weeds out sites for poor design, we’ve made some exceptions here to bring you as much information as possible on teaching high school geometry.
- We also usually avoid recommending sites that are mere directories of links to outside sources. In our education guides, we make exceptions to this rule for lesson plans and student activities to provide you with as much helpful content as possible. Make sure to approach every directory with caution and evaluate the links before using a tool in the classroom.
