● Conclude: Today, we learned about the If-else and Else-if blocks.

● Ask the following probing questions:

■ Can you differentiate when to use the if-else block and when to use the else-if block?

Possible Responses: When we have only one condition, we use the if-else block; When we have to check more than one condition and action, we use the else-if block.

■ Why do you think the last else does not require a condition?

Possible Responses: The last else is the last option that will execute whenever the previous conditions are false; If no condition is true, the last else block will be executed.

● Assign the following project as homework:

■ Input marks in English. Check the following conditions – If the marks are more than 90 print a message “Excellent”. If the marks are fewer than 60, print “You need to work harder”. If none of the conditions are true, print “You are doing well. Keep working hard!”
