# Lesson Plan of Ascending and Descending Order

## 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.
