Who's The Daddy?
Today, students solved the most ridiculous problem I've ever written. We've been working on writing exponential functions given 2 points and an asymptote the past couple of days in IM3. I wanted students to understand how useful models can be (they give us an equation we can plug values into). When students came in today, I gave them each a "case file" from "my lawyer friend" who wants their help in a case. Inside there were the following: a letter 2 plane tickets a patient lab chart a fake Wikipedia article Students then worked on solving for an exponential equation to model Amanda's HCG level using the information on the patient chart to create this, along with the info from Wikipedia to know that the asymptote is k=5. They can then use the exponential to work backwards and solve for the date of implantation (Feb 11), subtract 8 days to get the date of conception (Feb 3), and then subtract a couple more days to get the day of
