Subject Mathematics

Grade III

Students` Learning Outcomes

• Read Roman numbers up to 20.

Information for Teachers

• We use the following numbers in our daily life for calculation.

• Romans were using the following numbers for calculation:

• Roman numbers, as the name suggests, originated in ancient Rome.
• Roman numbers are written as combinations of these letters.

• These letters represent:

• Roman numbers can be written in capital (XVI) or in lower case letters (xvi).
• There is no zero in Roman numbers.
• While teaching the lesson, also consult textbook where and when applicable.

Material / Resources

Writing board, chalk/marker, duster, number flashcards, Roman number flashcards, chart of first 20 Roman numbers, a chart having a dial of a clock with Roman numbers, Mathematic textbook

Introduction

• Write first five Roman numbers on the board and ask the students:
• Have you seen these numbers written anywhere?
• After taking their response show the chart having dial of a clock with Roman numbers.
• Tell the students that these are called Roman numbers.
• Tell the students let us practice to read the numbers.

Development

Activity 1

• Write I, V, X on the board and tell the students that:
• “I” represents 1
• “V” represents 5
• “X” represents 10

• Tell the students that to read Roman numbers we have some rules.
• Repetition of letters (I, V, X) means addition.
• For example:

• When a smaller number is written to the right of a greater number, the smaller is d in the greater.
• For example:

When a smaller number is written to the left of a greater number, the smallere is subtracted from the greater.

for example:

• Write some Roman numbers on the board.
• Ask different students to read these Roman numbers.
• We can`t write more than three times any smaller number to the right of a greater number.
• For example: VIIII can`t be written.
• Carry on this activity to practice the reading of first twenty Roman numbers.

Activity 2

• Divide the class in two groups.
• Distribute 20 number flashcards to one group and 20 Roman number flashcards to the other group.

• Ask one group to show number flashcards and the other group to show the corresponding Roman numbers flashcards.

• Guide the students and correct their mistakes.

Activity 3

• Hang the chart of first 20 Roman numbers in the classroom.

• Ask the students to read Roman numbers from that chart aloud.
• Give chance to maximum students to read these numbers individually.
• Guide and correct their mistakes.

Sum up/ Conclusion

• There is no zero in Roman numbers.
• I, II, III, IV, V………… are called Roman numbers.

Assessment

• Write the following Roman numbers on the board:

• Ask the students to read them.

Follow up
