Great lesson! I really liekd that you started the lesson with questions for the students to answer. This will get them thinking about the material before you present them with the rules. I also thought the questions throughout the lesson were very good and that it was a GREAT idea to have the students pick the rule they used. The only one I thought may be a little confusing for students was 13000000. It is not very common to have a decimal without numbers after it. I understand that this will make two rules correct, but if possible you could make both of those a correct answer.
The flow of the material was very good, if possible I would recommend a little more annimation in some of the slides so that students are looking at all of the material without skipping straight to the question.
