The initial task is just for warm up - to program the robot to follow the black line the same way they did in the previous lesson.
Afterwards they will learn how to program a 3 state line following.
In order to program successfully 3 state line following they have 3 tasks - to measure the reflected light over the line, on its' edge and outside of the line. Then the program should look like this:
It is possible to use just one motor for the turns, but in such cases they should pay attention to stop the other motor. Otherwise the robot will move forward.

Level C1. "Transportation". Robotics with LEGO
This is the fifth level in the Robotics with LEGO curriculum for students in third or fourth grade.
For the first time robots with steering wheels are built in this level. Those robots use one or two drive motors. The work of the differential and its usage in vehicles is explored. Students learn in-depth the working of the light sensor to create better line-following programs. The first two-wheeled motorcycle-robot is built.
