Exponential Decay
This is the Radioactive decay investigation out of the discovering Algebra book. I retyped it to fill in some gaps and give a little more direction. You will need the following: [|Teacher InstructionsRadioactiveDecay.doc] [|RadioactiveDecayPaperPlates2.pdf] [|RadioactiveDecayPaperPlates2.doc]
 * One worksheet per pair of students (investigation done in pairs)
 * Paper plate for each pair with a central angle drawn on it that is 30 < x < 90 degrees.
 * Counters...beans! or any other counter
 * Protractor (can be shared by groups)
 * Candy for winning partners
