We investigate resources on TeachersPayTeachers and discuss how what is available affects our teaching practices.
This department provides a space for current and past PK-12 teachers of mathematics to connect with other teachers of mathematics through their stories that lend personal and professional support.
Melissa Graham, Johana Thomas Zapata, Amy Roth McDuffie, Nicole Blake, Introduction and Reflection by Angela T. Barlow, David Custer, and Clayton Edwards
Lesson study supports teachers in learning about curriculum and effective teaching practices. We discuss a district-wide lesson study process used to explore and adopt a new curriculum.
