Lesson Plan: I Can Do This! System of Equations - Grade Eight - Grade 08
Grade:08
Summary:Students solve systems of 2-by-2 linear equations using tables, graphs and substitution. The lesson builds on previous experiences with problem situations represented and solved using a system of equations. Students practice more formal strategies for representing and solving systems of equations.
