Activity I
1. Give each student a copy of his/her math grades for the
previous week.
2. Students will use a calculator to figure the mean (average),
mode, and median for their scores.
3. Have students eliminate the high and low score and refigure the
mean mode, and median.
4. Students write in
their journal to explain what happened to the mean, mode, and median.
5. Each student writes 2 questions that can be answered by the
information collected and then discusses those with other people in their
group.
Activity II
1.
Using the
information about TV viewing, each student will figure out his weekly
average for TV viewing.
2. Students will make a graph (their choice) to show the data
collected.
3. Students will compare their graphs with other student graphs.
Write in journals about how they are the same or different.
4. Working in groups, find the average TV viewing for the group for
each day of the week.
5. Using Excel, enter the average TV viewing for the group for each
day of the week and make a histogram and line graph to show the
information. Print out and write an explanation to go with each graph.
Papers should be put into Math Journals.
6. Write in journals. Students predict what will happen if the
eliminate the highest and lowest amount of time and then work the
problem. Was their prediction correct?
Activity III
1. Students work in
groups and find the mean, mode, and median bedtime for the class for each
day of the week.
2. Using a graphing calculator, students construct a box plot to
represent this information.
3. Write in journals to discuss which is the best representation for
showing the “center”.
4.
Class discussion about their findings.
Activity IV
1.
Class discussion questions
a. What have you learned?
b. Is there some way to put all of this
information together?
c. What predictions can be made?
d. What else would you like to find out?
2. Working as a large group, construct overlapping graphs to show
the three areas for which data was collected, using group information.
3. Discuss possible correlations about the data and its possible
uses and misuses.
Activity
V
1. Math
Journal Activity
In ice skating, skaters receive scores from several judges ranging from
0-10. The final score is calculated by dropping the high and low
score. Why would they drop 2 scores? Explain your answer. |
