Subject Mathematics

Students` Learning Outcomes

• Compare 2 or 3 –digit numbers (Hundred, Tens and Ones)

Information for Teachers

Material / Resources

Writing board, chalk / marker, duster, textbook, chart

Introduction

• Ask students if I have 10 rupees in one hand and 18 rupees in the other hand which amount is greater?
• Take their response and encourage them.
• Tell them that we compare any two numbers with the help of its place value chart.
• For comparison we start from left hand side.
• But in place value table we write from right hand side.
• Today we will learn how to compare 2-digit and 3-digit numbers.

Development

Activity 1

• Draw a place value table on the board and explain the students.
• In a 2-digit number we have two place values to be compared that is Tens and Ones.
• Tens are greater than Ones.
• So, first we compare Tens and then Ones.
• If we have same digit at Tens place we move to the Ones and compare its digits.
• In 10 and 15 we have same digits at Tens place so we get no idea which number is greater.
• So we move to digit at Ones place.
• We see that 0 is less than 5.
• Hence 15 is greater than 10.

Activity 2

• Write on the board 100, 200, 300, 400, and 500?
• Ask the students which number is greater out of these?
• Take their feed back.
• Make a place value chart on the board.
• Ask the students to observe the Hundreds column.

• Now call any student and ask him which number is the greatest? (500)

Activity 3

• Tell the students that comparison of any 3-digit number is just like the comparison of 2-digit number.
• In 3-digit numbers first we compare hundreds then tens and then ones.
• Draw the following chart on the board.
• Tell them that in 237 and 239 the hundreds place value is the same, so we check tens place, its same again.
• Now check ones place, it is different.
• Which number is greater out of 7 and (9)?
• Hence, 239 is greatest.

Sum up / Conclusion

• In 2-digits numbers first we compare tens and then ones.
• In 3-digits number first we compare hundreds then tens and then ones.

Assessment

• Compare the following numbers.
