lab set up such that:
Each computer has Microsoft Excel.
a computer monitor large enough for the entire class to see the"Lucky
Number" excel file during group discussion.
Number" handouts for each student
3 spinners, each equally partitioned with the digits 0 - 9
Pass out a
"Lucky Number" handout to each student.
2. Explain the scenario on the top of the handout.
OPTIONAL: use 3
spinners to demonstrate what is being simulated.
3.Give them time to individually complete the
"Before Opening the
Lucky Number File" portion of the handout.
Give them a short amount of time, because the object of these
predictions is to get an accurate portrayal of their intuitions and
4. Begin by opening up the
"Lucky Number" excel file on the
classroom monitor. Explain
the set-up that is described in the beginning of the "Before Running
Simulations" section of the handout.
5. Again, give them a short amount of time to complete the
Running Simulations" section of the handout.
6. Demonstrate for the class what happens when you press F9.
Demonstrate how to enter the your choice numbers into the
Have each student open up the "Lucky Number" excel file at their own computer.
8. Let them begin to work through the remainder of the handout.
9. Circulate continuously, paying close attention to answers on the
Once everyone has worked through the handout, display the excel
file on the classroom monitor. Have students generalize aloud what they
have learned about "lucky numbers".
Ask for volunteers and try out "lucky number" suggestions on
the classroom monitor. Use
this time to prove to students that "nice" numbers occur just as often
as "more randomly selected" numbers.
Show arithmetically that the likelihood of any given 3 digit number
occurring in this scenario is 1/1000.
Thorough examination of the handout both
during and after the lesson will allow you to get a feel for what students
are thinking about while experimenting with the simulation.
