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
