Instructional Ideas
- Use this slideshow to introduce solving systems of equation
- Modify the slideshow to include an example after each method is introduced
Classroom Considerations
- Some teachers consider the elimination using addition and subtraction and elimination using multiplication as one larger process (elimination/combination)
- There are no practice problems in the resource; develop some for your pupils as homework
Pros
- The lesson provides a step-by-step procedure to solving systems of equations
Cons
- The title is a misnomer as the lesson is about finding solutions to systems of equations
- No example is given for the substitution method, even though it is described in the lesson
