Always, Sometimes, Never

This professional development video ( video 1) from Minnesota Math and Science Teacher Academy Center in Region 11 presents an algebra training session on justification. Viewers watch Dr. Terry Wyberg, a methods professor at the University of Minnesota, discuss five statements after teachers have had an opportunity to decide if each statement is always, sometimes or never true and a reason why. Dr. Wyberg shares that in math a response of always or never mean you need justification. Justification is central to mathematics and even young children cannot learn mathematics without engaging in justification. He also presents information about the use of math conventions with the use of algebraic representation for his audience.

This resource is included in the following PD Collection(s):
CCSS Practice Standard 3This collection assists teachers as they integrate Mathematical Practice Standard 3 into their classroom routines. Encouraging productive student conversations about mathematics builds the foundation that supports this practice. These resources will help teachers learn methods for creating an environment where constructing arguments and critiquing the reasoning of peers is a common occurrence. Additional resources may be found in a companion classroom collection.
CCSS Practice Standard 6Common Core’s Mathematical Practice 6, Attend to Precision, calls for students to be clear in their reasoning, calculation, and communication through the precise use of words, symbols, units of measure, mathematical expressions, and processes. Students recognize various levels of precision and apply them appropriately; they calculate accurately and efficiently. These resources are intended to help teachers and math specialists understand the intent and scope of MP 6 and plan for successful attainment in the classroom. A companion Classroom collection, Implementing CCSS Practice Standard 6, includes resources to help teachers foster this practice with their students.

      Really great for PD

    • This video is really great to either show for PD or to use as an example for PD. In this video they discuss the importance of being precise with language and discussing "rules" in math class.
