The next unit in your child’s mathematics class this year is Moving Straight Ahead: Linear Relationships. In this unit, students are developing skills in areas that are traditionally known as algebra. This unit introduces them to situations that can be modeled with linear functions and graphed with straight lines.
UNIT GOALS
The primary goal of this unit is to develop understanding of linear relationships or linear functions. Students learn to recognize linear functions by the constant rate of change between two variables in a verbal context, table, graph, and equation.
Students identify, represent, and interpret linear relationships. They solve linear equations and write equations for lines. These last two ideas will be revisited with more complexities in later units—in particular, the Thinking with Mathematical Models and Say It with Symbols units.
