Development of Lesson:

      Introduction:

        We will discuss the definitions of the mean, median, and mode.

 

      Methods/Procedures:
      1. Students will count and graph the number of pieces of candy in their packs by color. Each student will graph his/her results.
      2. Use the above data to figure the mean, the average number of pieces of candy of each color. For example, if the data indicates 1 red candy, 2 green candies, 3 orange candies, 7 yellow candies, and 7 purple candies, the mean, or average number of pieces of each color is 4. [ (1 + 2 + 3 + 7 + 7) / 5 = 4 ]
      3. Use the data to calculate the median, or middle number. [3]
      4. Use the data to calculate the mode, or the number that occurs most frequently. [7]
      5. The students will record their data on a worksheet and graph their findings.
      6. We will compile all data and find a class-wide mean, median, and mode.

 

      Accommodations/Adaptations:

        I will assist any students with special needs in the counting of their candy.

 

      Assessment/Evaluation:

        They will turn in their worksheets and graphs for grading.

 

    Closure:

      Eat M&Ms!
