VIM 11 Different Equations Banner@2x.png

In this VIM module, you will see a class discussing Pool Border. Having determined y = 4x + 4 as one solution, the class begins to look for other ways to “see” the growth and find additional equivalent solutions. This module is part of a set of modules based on the Pool Border task.

The Module Learning Goals are to:

Examine the structural relationships between different ways of counting in a specific visual pattern.
Consider how task design/selection impacts opportunities for student learning.
Consider how a teacher might effectively launch a task so that students understand the mathematical purpose.

Video in the Middle

Video in the Middle (VIM) is designed to support professional learning for teachers of grades 6–9 with a mathematical focus on learning and teaching linear functions. VIM modules are centered around a rich mathematical task that engages students in examining aspects of algebraic thinking in geometric contexts. Each module follows an explicit learning trajectory in which a video clip is used in the middle of a set of learning activities composed of mathematical problem solving, video analysis of classroom practice, pedagogical reflection, and application to practice.
