7. Ask one student from each group to tell the total number of Skittles and number of red Skittles in their bag. List on board.
8. Explain and model to students how they will find the fraction of the red Skittles.
9. Explain and model to students how they will change the fraction to a decimal.
10. Explain and model changing the decimal to a percentage.
11. Tell students to complete all of the computations for their red pieces of candy after you have completed your model.
12. Tell students to complete the rest of ‘Part One’ on the chart. (group members can help each other if necessary)
13. Tell students to work individually to complete ‘Part Two’ by recording the comparisons of the highest and lowest percentages of each color recorded in their group.
14. Tell students to discuss whether they were surprised by the differences.
15. Tell students to complete ‘Part Three’ on their worksheet.
16. Select one student from each group to present their final numbers for ‘Part Three’ and to explain how they calculated the numbers.
17. Tell each student selected to make his presentation.
18. Tell students to turn in worksheets.
19. Tell students to enjoy the Skittles™!
20. Assess the worksheets.
AssessmentsAssess each student's worksheet for correct computations. Note those that have difficulty changing percents into fractions or decimals. This lesson doesn't address scientific notation, exponents, radicals and absolute values.
ExtensionsExtend this lesson by using the Skittles™ information for a graphing lesson.
Web LinksThe company lists that there is 20% of each color in the bag. Did the students find that to be true? It is up to individual teachers to decide how to use the Skittles product information in their classes. The website changes frequently. The site is for general information.
