8th grade: We spent last week on the concept of slope as rate of change. This is a building block for students to learn about the language of algebra and how we use that language to understand the world through relationships and patterns. This week we begin to study the symbolic language of expressions and equations as way to describe those relationships and patterns. We specifically focus on the concept of "like terms". Over the next few months we will continue to learn how these blocks and others like them come together as a mathematics literacy that helps us make meaning of our world.
