This curriculum unit will require students to read word problem scenarios involving linear relationships, and determine the relationship between independent (x) and dependent (y) variables. The problems will gradually increase in complexity as the unit progresses. Class discussions and related assignments will help lead to interpretation of a rate of change in relation to the slope of a line in a graph describing the scenario. Students will progress to recognizing rate of change in everyday situations and will eventually be able to interpret that rate of change using multiple forms: word problem scenarios, tables of values, graphs, and linear equations in slope-intercept form. Emphasis will be placed on understanding the relation between dependent and independent variables for linear functions.
