Graphic organizers can help students gather the required information to solve a problem. In calculus students work with problems where various rates of change are taking place in one problem. This package contains one graphic organizer to use when working with related rate exercises.
The graphic organizer is divided into five sections.
• The student should try to draw a picture or sketch to help show a relationship among all the variables in the problem. The student should include any appropriate variables and constants to their sketch.
• In the next section the students should identify which measurements are constants and which are variables. They should also identify all rates of change described in the problem and those that need to be found.
• Now the students should look for an equation that relates the variables and constants. Many times an area formula, the Pythagorean Theorem, a trigonometric ratio and volume formula might be appropriate to use.
• The student should look at their list of constants and variables and notice which of these change with respect to time and which are constants. The student should take their equation and differentiate it implicitly with respect to time to create a related rates equation.
• Using substitution the student should take their related rates equation and solve for the missing information.
The package includes examples for using each graphic organizer.
