## The Language of Algebra: Equations, Tables, and Graphs

Students explore the use of variables and expressions in solving problems as they work with equations, tables, and graphs. Students learn about variables and expressions as they consider what they would put into an ideal school. They then explore linear equations of the form y = mx+b on a graph.

### NCTM Standard: Algebra
