Students will learn how to convert between fractions, decimals, and percents using a computer applet and the concept of money.

- Recognize and generate equivalent forms of commonly used fractions, decimals, and percents;

*Technological*:

Students must be able to:- perform basic mouse manipulations such as point, click and drag.
- use a browser such as Netscape for experimenting with the activities.

Teacher will need to have a mock store set up in the rear of the class.

Students will need:

- access to a browser.
- pencil and paper.
- scissors.
- coin page print-outs.

**Focus and Review**
Review prior fraction material. Lead into this lesson by asking:
How many people in here like money?
**Objectives**
Student will be able to convert between fractions, decimals, and percents.
**Teacher Input**- Instruct the students to cut out their coins from the coin pages.
- Ask the class how they would see 25 cents written in a store. Have the student who raises his/her hand come write his/her answer on the board.
- Repeat this for 10, 5, and 1 cent/s.
- Instruct the students to separate their coins into pennies, nickles, dimes, and quarters.
- So we represent money using decimals. How many pennies are in a dollar?
Count out 100 pennies. Using your pennies tell me:
- What is 1/4 of a dollar?
- How did you calculate that?
- Can someone write on the board that for the class in decimal form?
- What is that equal to in quarters?

- What is 1/5 of a dollar?
- How did you calculate that?
- Can someone write on the board that for the class in decimal form?
- What is that equal to in dimes and nickels?

- What is 1/2 of a dollar?
- How did you calculate that?
- Can someone write on the board that for the class in decimal form?
- What is that equal to in dimes, nickels, and quarters?

- What is 1/10 of a dollar?
- How did you calculate that?
- Can someone write on the board that for the class in decimal form?
- What is that equal to in dimes?

- What is 3/4 of a dollar?
- How did you calculate that?
- Can someone write on the board that for the class in decimal form?
- What is that equal to in nickels and quarters?

- What is 1/4 of a dollar?
- Explain to the students that what they are doing is converting from fractions to decimals.
- Show the students how to convert from fractions to decimals by dividing the numerator by the denominator.
- Now ask the students a series of questions about percentages.
- Does anyone know how much 100% of something is?
- Does anyone know how much 50% of something is?

- Show the students how to convert between percents and decimals.

**Guided Practice**- Have a mock store set up in the class. In the store have the items on sale for example buy one $1.00 pencil get one 1/2 off.
- Pass out shopping lists. You will probably want to have several different versions of the list to avoid students clustering at the same stations.
- Have the students calculate a total for their list. You may want to offer a small reward for those who total up their list correctly.

**Independent Practice**- Assign partners.
- Demonstrate how to use Fraction Four.
- Have the students open the Fraction Four applet and begin playing it with a partner.

**Closure**- Discuss why conversions between fractions, decimals, and percents are important in real life situations.
- Review the steps used to convert between fractions, decimals, and percents.
- Review any new vocabulary.
