this culminating activity, students examine the set model using colored
candies. Give students an individual bag of colored candies, e.g.,
M&M's® or Skittles®. Have students open their
bag of candies and sort by color. Have students count the number of
each color in their set and record those data on notebook paper. Have
students record the fraction of each color represented in their
individual packet. All fractions should be reduced to lowest form.
Have students log on to the Create a Graph Tool
from the National Center for Education Statistics. Students should
choose the type of graph they want to create by using the pulldown
menu. Once students have created their graph, they should label the
data in fractional parts and reduce all fractions to lowest terms.
As a class, create a line plot of the number of candies in each bag. An example is shown below:
Have students determine the fractional representation for each
number of candies. For example, for the graph shown above there were:
- 2 students with 22 candies (2/16 or 1/8),
- 4 students had 23 candies (4/16 or 1/4),
- 5 students had 24 candies (5/16),
- 3 students had 25 candies (3/16), and
- 2 students had 26 candies (2/16 or 1/8).
Next, have students log on to the Circle Grapher to create a circle graph for the class data.
Fractional representations should be labeled. Ask students to
share their circle graphs with a neighbor. Discuss how a circle graph
is useful for showing fractions of a set. Some students may also
recognize that percents are also used in circle graphs. This discussion
would be a nice tie-in to percents, specifically fractions out of 100.
