Enhance pupil understanding of proportions and variable relationships by studying direct and inverse variation. Use the idea of a proportional relationship to teach direct variation. Then use a similar pattern to help individuals understand inverse variation.
- Use the second example as an opener and allow pupils to develop strategies to determine a solution
- Compare and contrast direct and inverse variation with your classes
- Builds from the previous lesson in this series on proportions
- The lesson concludes an 11-part series on fundamental algebraic concepts
- Uses real-life application to build the concept of variation
- Provides a set of practice problems that includes a problem-solving section
- Moves quickly to the formula for direct and inverse variation before developing an understanding of the concept
