# Ancient Story Problems

### Summary

Students will research ancient civilizations and develop story problems using symbols and coins from those times. Students will then retell these story problems using modern terms and coins. This lesson is part of the Unit Plan “Ancient and Modern Coins.”

### Coin Type(s)

- Cent
- Nickel
- Dime
- Quarter
- Half dollar
- Dollar

### Coin Program(s)

- Generic

### Objectives

- Students will create their own story problems based on people, symbols, and coins from ancient Greek and Roman times.
- Students will retell these story problems using modern terms and coins.
- Students will learn about the history of ancient Rome and Greece.

**Total Length**:
46-90 minutes

### Groupings

- Small groups
- Individual work

### Terms and Concepts

- Coin history
- Coins
- Greece
- Greek coins
- Roman coins
- Rome
- Story problems
- Writing

### Materials

- Access to the Internet.
- Web pages on ancient Roman and Greek coins
- Web pages on Roman history, coins, and technology
- Pencils
- Paper
- Books that give information about coins and coin making, such as:
*Roman History From Coins*by Michael Grant*North American Coins and Prices, 9th edition*edited by David C. Harper*Handbook of Ancient Greek and Roman Coins*by Zander Klawans*Facts and Fictions about Coins: An Uncommon Guidebook to the Wonderful World of Numismatics*by Leon Lindheim*Official 2001 Blackbook Price Guide to United States Coins*published by Random House, Inc.*Coins as Living History*by Ted Schwarz*Art In Coinage*by Carol H.V. Sutherland

- Tell the students that they will each be writing a math story problem using ancient Greek or Roman coins and settings, then a similar story in a modern setting. You can give the students guidelines (grading rubric) for which mathematical operations should be used in their problems and how many steps their problems should include.
- Divide the class into groups. Have the students use the internet sites or books to research the coins and times of ancient Rome and Greece and come up with a list of coins and items they can use in their story problems.
- Have each group write ideas on butcher or chart paper and post them around the room to share with other groups.
- Model the exercise with these examples:
- A Roman laborer earned one Denarius a day. A Denarius could purchase 25 pounds of bread or 10 pounds of olive oil. How many days would the laborer need to work to buy 30 pounds of oil? If he eats 2 pounds of bread per day, how many days does he have to work to buy bread for 50 days?
- A modern day worker makes 50 dollars a day. If a loaf of bread costs 99 cents, then how many loaves can he buy after working one day? How much money would he have left over?

### Differentiated Learning Options

- Students could create harder (multi-step) problems for enrichment.
- Story problems can be sent to another class at the same level via email for other students to solve.
- Students can use manipulatives to help them plan out their story problem, or they can also draw out the problem instead of writing it.

- Evaluate the story problems to see whether the students have met the lesson objectives.
- If you use a rubric, have it specify the number of steps, types of mathematical operations, and strategies for solving the problem.
