Interactive Spreadsheet and its Uses

The interactive spreadsheet, while not actually going according to plan, was a good assignment for me since I am not very good with Excel.(as can be seen) I like that students can do an assignment and instantly receive feedback on their answers, even if that feedback is just whether they are right or wrong. In this age of instant gratification it seems almost inadequate to give students an assignment that they have to wait a day or two to see the results of. With an interactive spreadsheet I can constantly be teaching the students such things as subject-verb agreement without actually having to look over their shoulders and see if their answers are correct. I would certainly be able to find many other uses for such a format of education.
