In this final lesson on systems of equations, students work in groups as they apply what they have learned to solve three problems with different structures and then create a new problem similar in structure to one of the ones they solved. Groups trade problems, prepare well-explained solutions, and take turns sharing their solutions with the class. While groups share, ask other students to interpret particular aspects of the presentation, such as the slope of a graph, the coefficient of a variable, or the solution to a system, in terms of the context of the problem. When students present solutions and critique other students' solutions, they engage in MP3.
- Calculate the solution to a system of equations in context, and present (using words and other representations) the solution method.
- Create a system of equations to solve a problem in context.
- Critique (orally) peer solutions to a system of equations.
Let's solve some gnarly problems.
Provide access to tools for making a visual display to each group of 2.
- I can use a system of equations to represent a real-world situation and answer questions about the situation.
