Who doesn’t love a candy math activity for Valentine’s Day? Candy math activities are always fun, but upper elementary and middle school teachers can use candy math activities to do some serious data crunching! I developed this Valentine Hearts Investigation when I was teaching 4th grade and my students loved it. The activity engages the class in collecting data from 10 boxes of colored valentine heart candies and making predictions about a new box. As they work, they apply statistical concepts such as range, mode, median, and mean. This activity comes with a Smartboard Notebook 10 file, but the Smartboard is not a requirement for teaching the lesson. Promethean boards users should be able to convert this file, and the lesson can also be taught with an overhead projector or chalkboard. You can download this freebie from my store on TeachersPayTeachers.com. I hope you enjoy it!
