Probability Kisses

Cheryl Carasick
Marion County Schools

Description

Students learn about probability by randomly picking a Hersey Kiss from a bag. They will be picking from a variety of colors. The students decide if they are less likely, more likely, or equally likely to pick a certain color based on the numbers of each colored kiss.

Objectives

The student knows if a given event is equally likely, most likely, or least likely to occur (for example, spinners, coin toss, election results).

Materials

-Paper bag for each student with ten various colored kisses and one for each student with class activity
-One rubric for each student (see attached)
-One worksheet for each student (see attached)
-Pencils

Preparations

Prepare bags of kisses for each student with ten kisses in each bag. Randomly put ten kisses in each bag. Place the studentsí names on the bags and record the number of silver and gold kisses each student received. Have one worksheet, pencil, and rubric ready for each student.

Procedures

1. Review the definition of probability (chance).

2. Discuss the following definitions to ensure understanding: "likely," "more likely," "less likely," and "equally likely."

3. Tell the students that today they will be determining the probability of picking out a certain number of different colored candy out of a bag.

4. Tell the students that the class will first do one together. Show the students that there are five silver and five gold kisses in the bag. Ask students if there are equal amounts of each kisses. Ask the students if it is less likely to pull silver than gold, more likely or equally likely.

5. Give the students time to discuss what they think the outcome will be.

6. Pull ten kisses out randomly and record the results.

7. Redo the activity with the students. This time show them that there will be two silver and eight gold kisses. Ask the students if there are equal amounts. Then ask them if they are more, less likely, or equally likely to pull a silver kiss out of the bag.

8. Randomly draw ten kisses and record the results.

9. Put nine silver and one gold kiss into the bag. Ask the students if they are less likely, more likely, or equally likely to pull a silver kiss out of the bag.

10. Randomly draw ten kisses and record the results.

11. Discuss the three different results with the students.

12. Distribute bags of kisses to each student(each student should have a random amount of colored kisses in their bag. They each should have a total of ten kisses in their bag.)

13. Hand out the worksheet titled "Hershey Kisses". Inform the students that they will be using this sheet to record their data.

14. Have the students complete their worksheets while they randomly draw ten kisses out of their bag.

15. Discuss the individual results with the entire class.

Assessments

Students will be formatively assessed on their abilities to identify if a given event is more likely, equally likely, or less likely to occur. The students will receive feedback via the attached rubric, based on the worksheets the students complete.
