Snapshot: 7A Variables & Expressions

The seventh graders are grappling with making the leap from concrete numbers to abstract algebraic symbols. This transition is developmental and is nurtured by regular exposure to patterns and looking for connections to the concrete examples. This week, 7A was working out the concept of like algebraic terms. How is x different than an x squared? What does 2x mean? How do we do operations on like and unlike terms?  These the foundation the algebra that is to come.
