3.++Process


 * ===Instructional Plan=== ||

If students need help with a spreadsheet, help them record the independent variable values in the left column, then in the next column, use their function to calculate dependent variable values. In the next column, starting with the second piece of data, calculate percent change using the following formula: Students should then copy the formula down the column. If some students tend to be the "computer experts" and are doing all of the work while other students are disengaged, try having the "experts" become teachers. Have the students who are sitting back be the ones who work the keyboard and mouse while the experts instruct the workers in what to do. || The National Debt as Wars Activity Sheet
