 Explain to students that the next section 

of code is part of a program that controls a robot 

from a mobile phone. Pressing different keys on 

the number pad makes the robot move forward, 

backward, or turn left or right.  

 

Ask students to look at the code (which is in the 

C programming language). Tell them they do 

not need to understand it yet but they will hear 

two programmers talking about it and will have 

to identify features while listening. Elicit from 

students that g_Turn, g_Move and key_Press  

are variables.  

 

While listening, students write numbers in the 

boxes below the code to indicate the order they 

hear these variables mentioned.
