## Hands & Hearts ~ A Mean Combination

Using Conversation Heart candies, students review and strengthen their understanding of estimating, sorting, graphing, mean, median, mode, fractions, decimals, and percents. Additionally, students get a chance to eat some candies with funny messages, but not until they have finished the math lesson.

### The Activity
