I always like to have a student fly figure 8's so that they learn left and right input. As for landing, have them fly approaches keeping the wing level and lining up on the center line of the runway. They will also need to manage speed so using the throttle becomes important. With my students I will talk them through a number of approaches with each one getter lower than the previous. I have discovered that the student is not really aware of what is happening and before they figure it out they have landed. This will also teach the art of using power to go around and abort a bad approach. Kids will always learn quicker than adults so keep that in mind as well. Good Luck, Dave
