Bennett / Burton / Nelson Taking a Chance Applet

Go to the BBN Student Center Page of Interactive Math Applets by clicking here .

Select the Chapter 5 applet--Taking a Chance. Once you have launched the applet, play around with it a bit to see how it works.

See how many cards you can win in this game which involves both chance and strategy. Your understanding of fractions and knowledge of the deck of cards will help improve your strategy.

Chapter 5 Online Assignment

1. Play the applet at least 5 times and record your results. Write down what happened every time you made an error. If you won every time, explain why.
2. Comment on the applet. What strategies did you use? What errors did you make? Did your errors decrease over time?

Select the Chapter 6 applet--Competing at Place Value. Once you have launched the applet, play around with it a bit to see how it works.

Play against a friend or against the computer, but to win at this game you must be able to create the larger decimal from given random digits.

Chapter 6 Online Assignment

1. Play the applet at least 5 times and carefully record your results. Try to write down what happened every time you did not win. If you won every time, explain why.
2. Comment on the applet. What strategies did you use? What errors did you make? Did your errors decrease over time?

Bennett / Burton / Nelson Distributions Applet

Go to the BBN Student Center Page of Interactive Math Applets by clicking here .

Select the Chapter 7 applet--Distributions. Once you have launched the applet, play around with it a bit to see how it works.

As a tile moves randomly across a grid, you are challenged to predict the square at the opposite edge of a grid upon which the tile will most likely land. It is interesting that such random movements when applied to many tiles produce dependable patterns.

Chapter 7 Online Assignment

1. Run 9 experiments--note you have to choose "Start Experiment" and then "Spin" or "Autospin" to complete an experiment. The spin color determines whether the tile moves left or right. Change the number of outcomes and the number of chips several times, use 7 outcomes and 64 chips at least once (use Autospin!).
2. Record your results; you may wish to print the pages (check print preview; if regular printing doesn't work, use the PRINT SCREEN button, then print). Include diagrams of the finished grid and the corresponding bar graph for each of your 9 experiments. An example diagram is shown here:
3. Experiment 1--7 outcomes, 64 chips

4. Answer the question posed in the applet:

"For each type of grid and for 128 chips, predict the number of chips on average that can be expected to land in each of the lettered outcomes."

Explain your answers, you should have 6 sets of answers: 2 outcomes/letters, 3 outcomes/letters, 4 outcomes/letters, 5 outcomes/letters, 6 outcomes/letters and 7 outcomes/letters and for each answer set you should predict the number of chips on average that can be expected to land in each of the lettered outcomes. Hint--you can't just double your 64 experiment outcomes. Look at Math Activity 7.1 in the Conceptual Approach for ideas--counting the number of possible paths.

You may type or neatly hand write this assignment.

You may remember the TV game show where the contestant chooses 1 of 3 doors to try for a prize. The host then opens one of the remaining doors with junk behind it and asks if the contestant wishes to stick with the original choice or switch. Try to discover the winning strategy.

Chapter 8 Online Assignment

1. Pick ONE strategy: Stick or Switch and play the applet 20 times and record your results.
2. Change your strategy to the other choice: Stick or Switch and play the applet an additional 20 times and record your results.
3. Comment on the applet. What is the better strategy?
