Understanding Sequences and Functions

The video explores two standards from the interpreting and building functions domains, focusing on sequences as functions. Students learn to write arithmetic and geometric sequences, model real-life situations, and translate between recursive and explicit forms. The video highlights common misconceptions and showcases student engagement in mathematical practices. Tasks like microbial growth and counting quilt blocks are used to illustrate these concepts. The video concludes with a reflection on teacher questions and student risk-taking.
