Big Ideas:
Choosing the right method can help solve a system of equations more efficiently.
Students will look at four systems of equations and choose either graphing, substitution, or elimination to solve. They will compare with other students and determine the most efficient method of solving each system. This lesson plan builds from previous lessons that give students the methods for solving systems, and leads toward work with systems of non-linear equations.
Vocabulary: system of equations, elimination, substitution
Special Materials:
graph paper
ruler
