Complete lesson, start to finish at your finger tips. The lesson introduces solving systems by graphing by hand and by calculator. I have included a foldable with the TI-84 Steps and one with blank calculator steps for those with other calculators. The foldable is a great guided practice, the interactive notebook is a great way for students to collaborate and create and manipulate, the practice sheet can be used to reinforce, and I find exit tickets KEY to the assessment process. It allows me to see who has it and common misconceptions that I need to fix.
