There is yet another Oreo...
This activity builds off the work that Dan Anderson's math class revealed about Original Oreos and Double Stuff Oreos. Students begin by working with the weight of just the Oreo wafer and the total weight of an Oreo cookie in order to determine the weight of the Oreo's "stuf" (the unknown). Is the Double Stuf actually double the stuff? Then students repeat the process with data from the new Oreo Thin. How "stufy" is the new Oreo Thin? Students consider the ratio of "stuf" to wafer in the Original Oreo, Double Stuff, Triple Stuf and Oreo Thin and rank the four from least to greatest in ratio of "stufiness". Consider extending the investigation in your class to the Mini Oreos (bring in Mini Oreos, grab some scales and conduct some research) . The last part of this activity is to look at a long extinct oreo cookie called the "Big Stuf". Show the video below to your class when you get to those last questions.
