Smart lesson

I am planning a lesson for ratios in which I will use a smart board to draw and create examples on for the students to help me solve. I will be talking about rates and perceptions and the difference between the two. The students will also be doing textbook questions and assignment after so I can assess them. But I think using the smart board will help the students remember and get them involved to come up and solve or match certain fractions with their group. I might do some mental math in the future (math mad minutes) on the board to save paper and the students solving the questions but I haven't thought it through yet.
