Description

In this lesson, students will learn about Roman Numerals.

Goals

Students will learn:
About Roman Numerals
How to solve problems

Materials Needed

Worksheet I have included in this lesson
Pencils and Erasers

Procedure

First, you will copy the worksheet I have included in this lesson.

Then, you will explain to the students about the different Roman Numerals.

I = 1 V = 5 X = 10 L = 50

C = 100 D = 500 M = 1,000

You will also explain that when you place a smaller number in front of a larger number, you will subtract.

For Example: IV = 4

If you place a larger number in front of the smaller number, you will add.

For example: VI = 6

After that, you will write examples on the board so that the students will know how to solve the problems in their worksheet.

Examples:

XII = _______ IV = ______

XV = ________ LC = ______

After you explain the examples, then you will pass out the worksheets to have them work independently. Worksheet - Roman Numerals
