Elementary mathematics topics such as place value, properties of operations, and measurement lay the foundation for the math content that students will study in middle and high school. Elementary teachers can teach these topics most effectively when they possess not only common mathematics content knowledge—mathematical knowledge commonly used by many people in a variety of settings—but also strong specialized mathematics content knowledge that is specific to math educators and knowledge of how current mathematical topics connect to the broader mathematical landscape.
In this 30-minute recorded webinar, we discuss how elementary teachers can deepen their specialized mathematics content knowledge and their knowledge of the mathematical horizon.
