Sixth graders learn three ways to describe the “center” of a data set — the mean (average), median (middle), and mode (most common) — plus the range, and when each one tells the best story.
Students will be able to…
You want ONE number to describe a whole set of test scores. Should it be the average, the middle, or the most common? Each tells a different story!
Project this and tap each measure. Have students learn how mean, median, mode, and range each describe a data set!
Tap any phase to open the teacher moves and student actions.
