Return to Bring Ancient History to Life!

Brief Description

Objectives

• learn about Roman numerals.
• solve simple math problems using Roman numerals.
• create charts of Roman numerals and their Arabic equivalents.
• use an online Roman numeral converter. (optional)

Keywords

Materials Needed

• Doing Math the Roman Way student work sheet (provided)

Lesson Plan

Introduce students to Roman numerals. The following resources can be helpful:

• Ask Dr. Math: Roman Numerals
• Roman Numerals 101
• On Roman Numerals
• Roman Numerals Lesson Plan

After students have developed an understanding of Roman numerals, introduce the Doing Math the Roman Way student work sheet. Distribute a copy of this reproducible sheet to each student.

Extension activities:

• Have some fun with Roman numerals using the online Roman Numeral Converter. If a classroom computer can be hooked up to a projector, you might use this tool to create a fun, whole-class interactive quiz game.
• Make a list of places where you have found Roman numerals used.
• Create a chart of Roman numerals and their Arabic equivalents. For example, I = 1. Students could create their own charts.

Assessment

Students correctly solve at least eight of the ten Roman numeral math problems on this lesson's student work sheet.
