Her (both of our's really) plan was to use a PowerPoint from last year to introduce quadratics. Remember, this is the Monday morning after a 3 week break. So it was either leave her hanging to wing class sans technology or bring her class into my room and squish the students all together. We went with the latter and it was actually a great lesson.
However, it really made me realize how dependent upon technology in the classroom we are becoming. I had my first formal observation in the weeks before break and one of the comments I got was on how well I used my SMART board. While I don't feel as though I'm doing anything revolutionary, it is hard for me to imagine teaching without it. It's easy to save all my lessons as pdf files and then post them online for students to access (the perfect solution to "what'd I miss?") While teaching it's easy to go back and say, "Remember this? We talked about it <10 minutes ago>,
Today I had students looking at a "Deal with the Devil" type problem where the devil offers you $1000 today, but at the end of the day he takes $100 commission leaving you with $900. Tomorrow though, he'll double your money (giving you $1800) but will also double his commission and remove that at the end of the day. And the question was, would you take this deal for a month? By day 8 the numbers start to get big. And I would immediately turn to a spreadsheet to help with the calculations. But this class I was working with all groaned and said that they "hated" it. And then told me that they would just type the numbers in rather than having the spreadsheet make the calculations. These students are 16/17 years old! I'd assumed that they'd be comfortable with entering formulas by the time they got to me. But I guess not. And I guess it's up to me to turn their hate into love.
By the way, at the end of day 10 you're left with zero dollars. So remember, it never pays to make deals with the devil.
