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.

These the foundation the algebra that is to come.
