Math Update: October, 2025

We just finished our unit on one-variable statistics. Right now, the students are examining solving and graphing linear equations and systems of linear equations.

The unit builds on learning from 7th grade, where students used variables to write equations, manipulated equations using valid moves such as the distributive property, and solved basic systems of linear equations using graphs and substitution.

In the first section, students recall writing equations to represent situations. In the second section, they use valid moves to write equivalent equations that can be used to solve for unknown values or to isolate variables. The third section examines solving systems of equations using graphs, substitution for variables, and elimination of variables. Students use their understanding of writing equivalent equations to understand why each of the methods works for finding the solution.
