**Objectives**

- Students will be able to comprehend the value of a penny, nickel, dime, and quarter through lessons and research.
- Students will comprehend the concept of counting via researching and planning a sales event within their classroom.
- Students will count out color coded beads.
- Students will research the typical primary school child’s wrist size.
- Students will plan an event in which they create and sell the beaded bracelets in exchange for coins in their classroom store.
- Students will predict and compare final results for the sale.
- Students will be able to monitor the sales of the bracelets in a spreadsheet.
- Students will be able to evaluate the success of their bracelet sales after the event.

**Procedure**

- Using the Internet and projector in a whole group activity, view the following Discovery Education Video entitled Counting Coins, or have students research movies and/or articles online that deal with the same topic.
- After viewing the movie, allow students to see and touch the real coins (or manipulatives). Have the students create an activity in groups of 2 or 3 in which they devise combinations of values for each coin.
- Using Google Spreadsheets or other shared Internet collaborative applications, show students how to create a new file, name it, and share it with one other student and the teacher.
- Have students create their own spreadsheet in which they write the formula for each coin with a value higher than a penny in a separate cell. For example, Nickel=5 pennies.
- Discuss a class project of earning money for a purpose. Propose options. Guide discussion to creating and selling bracelets or another item.
- Facilitate class discussion on how the money will be used. Students should choose.
- Give each student a strand of beading twine and clasps (*Optional-Have students and parents go to a local bead store to see if they will donate necessary supplies for the school project as a charity donation).
- Using three popular search engines (Examples: Sweet Search, Ask, Quintura), have students research the average wrist size for a primary grade child, measure the twine with the appropriate unit of measure and with the average wrist size in mind Then, determine the number of beads needed for each bracelet. Each student should make a total of four bracelets (this can be finished as homework). This should give you roughly 100 bracelets that can be sold.
- Students create a plan for when/where they will sell the bracelets. (Example: Lunch time, after school, recess - with prior approval from the principal, et. al) Could use Google Calendar, sharing a class calendar for the planning and monitoring of the event.
- have students brainstorm other needs for a successful sale. Could include:
- Need for a treasurer to keep track of the money collected; allow students to vote or choose.
- Determine the price for the bracelet (teacher assistance required). Have students record their prediction for the amount of money the class will make; can be done with partner or small group.
- Consider any necessary advertising for the sales event and have students plan and execute this if possible. Option: could be an out of class assignment.
- Ending date for sale.
- While the sale is in progress, each student will keep a log of his/her sales on the shared spreadsheet with the coin values. The teacher can assist in the whole class evaluation of the total number of sales per day as well as the total amount earned.
- Show students how to add the numbers or have the spreadsheet run the tally for them.
- When the sale is finished, allow the students to evaluate the success of their bracelet sales by looking at the final numbers. Did everyone sell a bracelet? Was a bracelet lost? How does the amount sold compare with their prediction? *Optional-Students can also look at the cost/benefit analysis if they helped in buying the bracelet supplies.
- Use, distribute money as was decided by class.

**Materials**

- Computer with Internet connection
- Google Applications (or other open source spreadsheet application such as Chartle chartle.net/ or Chart Gizmo chartgizmo.com/) accounts set up for teacher and students (*Microsoft Excel or Apple Numbers can work as a whole class assignment with group work)
- Projector
- Interactive whiteboard, optional
- Student computers with Internet connection (computer lab or mobile cart with at least 1/2 of the total number of students for shared documents and research)
- beading supplies (beads in school colors-enough to make 100 bracelets, twine, clasps if necessary)
- coins or simulated coins
