## Reflection: Learning Communities Evaluating Expressions - Section 2: Guided Notes + Practice

This lesson was influenced by the collaboration between the Math teachers of 11th and 12th grade students. They found a gap in understanding was being created when students were taught the terminology “plug in” versus substitute. “Plug in” is not an operation in math, therefore the consistent academic language is a key component of this lesson. Saying “substitute” supports students when they learn systems of equations in Algebra 1 and Algebra 2.
