I am looking to PBL my way into exponents this year for my Algebra Students. I am dabbling with the idea of bacteria and patterns. Having read segments of Chaotic Fishponds, by Richard Elwes,there is an excerpt that might be a jumping off spot. Also today, I came across Everyday Einstein with Sabrina Steirwalt after reading a Scientific American Article, “Does Soap Really Kill 99.9% of Bacteria” . So, with this, I am going to get to work on a problem for my kids… I love the quiz about the # of germs on my cell phone – seriously gross!-and will be able to bring this into my Math 8 class as we discover the excitement of organizing numbers with Scientific Notation and exponents as well.
Stay tuned for more on the results of my mental conundrums with this PBL and where I go from here…. Love any thoughts that you’d like to share as well!
