Lesson Plan of Ascending and Descending Order
Subject mathematics
Grade III
Students` Learning Outcomes
 Write the given set of numbers in ascending and descending order.
Information for Teachers
 In ascending order we arrange the numbers from smallest to the greatest.
 In descending order we arrange the numbers from greatest to the smallest.
 To arrange the numbers in ascending or descending order we compare place value of the given numbers.
 While teaching the lesson, also consult textbook where and when applicable.
Material / Resources
Writing board, chalk/marker, duster, number cards of 1000, 2000, 3000, 4000, 5000, textbook
Introduction
 Write the following numbers on the board: i
 Ask the students to compare these numbers and identify the smallest number and the greatest number.
 Collect their response and elicit that 567 is the greatest number and 356 is the smallest number.
 Now ask them to arrange these numbers in two ways:

 Smallest to greatest
 Greatest to smallest

 Collect their response and demonstrate that we arrange numbers smallest to greatest as: 234, 356, and 456.
 Tell them this order is called “ascending order”.
 We arrange numbers greatest to smallest i.e.: 567, 456, 356, and 234.
 Tell them that this order is called “descending order”.
Development
Activity 1
 Select five students from the class and distribute the number cards of 1000, 2000, 3000, 4000, and 5000 to them. They will show these cards to the class.
 Now ask to arrange them from smallest to greatest. (They will stand in a way to show:
 Ask the other students to name this order. (Ascending order)
 Select five new students and distribute number cards of 1000, 2000, 3000, 4000, 5000, to them.
 They will show these cards to the class. Ask them to arrange themselves from greatest to smallest.
 They will stand in a way to show:
 Ask the other students to name this order. (Descending order)
Activity 2
 Demonstrate the method of comparing the following numbers in front of the students in the class room.
 Ask the students to copy and circle the greatest number and tick the smallest number in each box.
 Check their work and guide where necessary.
Activity 3
 Demonstrate the ordering of numbers in ascending and descending order to the students, for example:
Activity 4
 Write the following numbers on the board.
 Ask the students to copy and arrange the numbers in ascending and descending order.
Sum up / Conclusion
 Conclude that:

 In ascending order we arrange the numbers from smallest to the greatest.
 In descending order we arrange the numbers from greatest to the smallest.
 To put the numbers in ascending or descending order we compare all the given numbers.

Assessment
 Ask the students to arrange the following numbers in ascending order.
 Ask the students to arrange the following numbers in descending order.
Follow up
 Ask the students to:

 Arrange the following numbers in ascending and descending order.



 Tell what is the greatest 4digit number?
 Tell what is the greatest 5digit number?
 Tell what is the greatest 6digit number?
