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.

Grading

• Each question receives five points.
  
  100 to 90 = A
  
  89 to 80 = B
  
  79 to 70 = C
  
  69 to 60 = D
  
  Below 60 = F
