Conclude the session Assign the homework

● Instruct: Go to the Panel and open the Lab on Strings II.

● Play the video given in the panel.

● Discuss the Quiz questions given in the Panel.

● Invite answers from as many students as possible.

● Conduct Solved Example given in the Coding booklet on Page 26:

■ Say: Let’s check the length and case of our favourite movie.

■ Instruct: Click on the Assignment section.

■ Instruct: Click on the Go to Practice button to attempt the activity.

■ Walk around in the classroom and observe the activity done by the students.

■ Instruct: Click on the Yes button to submit the activity.

Note

● If time permits, conduct the additional activity given in the panel.

● Ask the following probing questions:

■ What will happen if a string is entered in all capital letters and we try to convert it to uppercase?

Possible Responses: It will remain as it is because it is already in upper case.

■ What is an empty string?

Possible Responses: Empty strings don’t have any value in them, not even a space! Their length is 0.

● Assign the following project as homework:

■ Input 2 Strings. The words of both strings should be the same but the cases should be different. Example → S1=”newt” while S2=”NEWT”. Now, compare the Strings and see if they are equal or not.

Note

● The project is optional. Assign it if feasible.
