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.
