A lot of money is going to be changing hands while the fair is running, so knowing how to work with percents is going to be really important. Whether it's sales tax, discounts or sales, the staff of the fair need to understand what is going on when percents enter into the picture.

In this module, you will be working on how we work through a percent problem as easily as possible. Many of us remember the basics of percents, so we're just going to springboard off of that and show you some more intuitive ways of working with them.

Activity 1: Team Discussion

Even at a County Fair you still have to collect State sales tax on items sold. So a $1.50 hot dog won’t be just $1.50 but will have tax added to it. Also, near the end of each day vendors often discount items, even ride tickets to sell as much as possible that day. As a member of the committee for the Fair, you will need to determine how much sales tax you will need to collect to send to the State. You will also need to think about discounted tickets to encourage more ticket sales and whether you want to make any other discounts on the final day of the fair.

You will also need to think about discounted tickets to encourage more ticket sales and whether you want to make any other discounts on the final day of the fair.

Discuss how you will solve this problem. What additional resources and information do you need? How will you explain your solution to the committee?

Activity 2: Percents and Decimals

With a partner work through the Module 8 Instructions on What is a percent and percents and decimals.

Then each partner should make up a list of decimals and percents. Then exchange lists and see if you can complete the conversion. Make them challenging. If you have difficulty, go back to your resources for help.

Activity 3: Percents and Fraction

With a partner work through the Module 8 Instructions on percents and fractions.

Then play the games to practice.

Activity 4: Working with Percents and Applications of Percents; Interest

With a partner work through the Module 8 Instructions on working with percents.

Go through each video on specific applications.

Then work with your partner on finding interest. Then each partner should make up a list of problems on finding the cost based on interest. Then exchange lists and see if you can complete the conversion. Make them challenging. If you have difficulty, go back to your resources for help.

Project Assignment:

Even at a County Fair you still have to collect State sales tax on items sold. So a $1.50 hot dog won’t be just $1.50 but will have tax added to it. Also, near the end of each day vendors often discount items, even ride tickets to sell as much as possible that day. As a member of the committee for the Fair, you will need to determine costs and income projected for the fair. You will also need to think about discounted tickets to encourage more ticket sales and whether you want to make any other discounts on the final day of the fair. To complete this task, work through the step-by-step directions on the worksheet.

1. Download the Task 8 Worksheet
2. Determine how much projected sales tax will be sent to the State.
3. How much effect discounting ticket sales could have on the total cash made on the fair.
