This article “Is 2 Really Greater Than 1?” we see how you can use Geogebra to have students create models that represent situations in the real world. Direct instruction, group work, and a worksheet are all used to get the students involved in the process of finding the correct answer to the problem; is two wheels more efficient than one? Students will work together to create a model that represents the size of a wheel, the size of the tire, and the ultimate cost of the bicycle and the tricycle using Geogebra. At the end of the assignment sheet, students will be asked to explain the difference of cost for certain materials. This allows them to make a further connection to the problem by understanding where the independent and dependent variables came from.

Here is the lesson plan that explains how to teach the modeling activity 2 >1 Lesson Plan and here is the worksheet used for this assignment 2 >1 Worksheet. To grade the students, you can use this rubric 2 > 1 Rubric
