We were working on creating towers! Then we counted the levels (yes, our towers had to be on their sides), counted the pieces of steel (our steel looked like toothpicks), and worked on equations. The level of the tower was the Independent Variable, the 'steel' was the Dependent Variable, and the difference in every level was the coefficient.
Independent Variables, Dependent Variables and Equations about their Relationship to each other3/9/2015 Along with creating tables and graphs, the students are also working on translating problems (like the one in the picture) into equations. They must identifiy the two variables (independent and dependent) and then the coefficient. This all sounds incredibly important (especially that coefficient), but it is not. The dependent variable is determined by what happens to the independent variable (and that what happens is the coefficient). Examples: How many miles you drive (the dependent variable) is determined by the number of hours (independent variable) you drive AND your average speed per hour (the coefficient) or distance = time x mph.
