Activity 2
1. In this activity, students will use DICE
and the TI-83 calculator, and will do the same experiment
that they used in Activity 1. This time they will assign a number 1-6 to each
color on the spinner.
This spinner has 2 red spaces.
Example: 1-orange
2-green
3-blue
4-yellow
5-red
6-red
2. Students will run the program using a six sided die and 25 trials. Students need to figure the ratios and experimental
probability for each color. Then, they will get the totals from the other groups, sum the
totals for each group, and figure the experimental probabilities for the grand total. They
should keep a record of their results in their math journal.
3. In their math journals, students will compare
their answers from activity one and activity two, noting likenesses and
differences in probabilities and discussing their own perceptions as to
why they are different or the same.Activity 3
1. Without spinning spinners with 3 colors, students will brainstorm how
they could determine the experimental probabilities of landing on each
color. Have the students to find a way to do this activity using the DICE program.
2. Have students carry out the same activity (as in activity 2) by assigning
2 numbers to each color.
3. Students will figure ratios and experimental probabilities for individual
group totals, and grand totals for the entire class.
4. Write in Math Journal about their conclusions and what they have learned.
Activity 4(computer lab)
1.
Discuss random numbers and show them how to generate random
numbers, using Excel.
2. Discuss ways that random numbers could be used to determine the
experimental probability of the spinner with 3 divisions. To make this easier,
let them use 60, 90, and 120.
3. Students will generate the random numbers and
determine probabilities for each color. Data will be kept in their
math journals. Included should be an explanation of what occurred.
Activity 5
1. Problem: McDonald’s has come out with a new series of 6 Harry Potter
toys in their Happy Meals. Many children and adults want to collect all of the
new toys that come in the Happy Meal Box. What is the experimental probability
of getting each of the toys? Design an experiment using what you have learned
to determine the probability.
2. Extension: How many Happy
Meals can a person expect to buy before they get all 6 toys?
