Sometimes you need a hands-on mathematics activity or you and your students are going to run screaming out of the room. But it's got to be a real application of math, not just a fun activity. This practical application is quick to set up and generates lots of student conversation. You can use it in lower grades to reinforce the concept of percent.
Students will determine the percent sugar in a piece of gum. (Dubble Bubble is readily available in grocery stores. $5 gets you 138 pieces.) All you need are food scales or balances from your favorite science teacher. It’s easy to control (less mess than you’d think) and generates a little excitement. The activity takes 55 minutes including the introductory PowerPoint, student measurements and calculations.
You get a power point about chewing gum to drive the activity, student handouts, a key, and teacher instructions that include ways to manage the mess so that it never happens. :)
