This activity will focus on the basic concepts of elementary Algebra. The student will apply the basic definitions and theory related to graphing data. Terms such as independent and dependent variable, slope of a line, line of best fit, plotting points on a coordinate graph will be discussed.
The teacher should introduce and discuss the basic concepts to their students prior to each student completing the activity. As an optional activity when calculating the “line of best fit”, the student may use a spreadsheet software such as Excel to generate the graph and equation for the “line of best fit”. The “How to Incorporate a Spreadsheet” teacher’s manual will be included for the teacher to present to their class.
Concepts to be discussed prior to assigning this activity booklet include:
1. Definition of dependent and independent variable.
2. Calculating the slope of a line.
3. Graphing data on a coordinate axis.
4. Calculating an equation for the “line of best fit”.
5. Projecting future outcomes applying your equation for the “line of best fit”.
