Is the application of systems of equations giving your class headaches? Use this resource to build on your pupils' logic to lead them to building equations and using algebraic methods. The lesson begins with an exploration of solving application problems using any method. As the comfort level increases, examples become more complex and eventually conclude with a problem using a system of inequalities.
