This is an activity created to practice probability while incorporating Valentine's Day. Each student or group of students will need candy conversation hearts. You can either give them an entire box or open the boxes and give each a specific number. I did the latter and gave every group 20. If you do this, you will need to put them in some sort of bag or container so that they can draw out the hearts without seeing them.
The first part of the activity asks students to group hearts, first by color and then by message and record the number of each. This will help them answer questions during the activities and will help the teacher when grading since every group will have different data.
Next, students calculate the theoretical and experimental probability based on the messages on the hearts. They are also asked to write a statement comparing the two probabilities as they relate to a specific message (ex. Be Mine).
Finally, students calculate compound probabilities of selecting multiple hearts. (ex. probability of pink and then green). They are also asked to create and solve a question of their own.
