Variables and Patterns is the first unit in the Algebra Strand. It is the foundation for understanding variables, functions, and equations. The unit focuses on describing situations that change, i.e., the distance of a car from home during a trip. Students learn they can represent situations in three ways: with a description in words, with a data table, and with a graph. Once students have mastered these representations, they are moved into writing these situations in symbolic notation, i.e., as an equation. Students are also introduced to graphing calculators. They use them to compare various situations and what happens to the situation when one variable is changed.
