how do i teach a noob rider to run the clutch?

[dank]

one of my friends bought her first bike yesterday, and we were out riding today. she spent almost a half hour trying to get the bike to go forward, rider error where when the clutch starts go engage, she drops it and it kills. its a kx100 btw. i tried to explain the balance between throttle and clutch, but im looking for a better way to show her. she puts the throttle at one speed and hopes it will get her through. i think she is also a bit throttle shy, because i moved her from next to the garage to out in the middle of the yard, and she got going long enough to keep it alive for a field road run. so is there any way i can help her to learn that balance between the clutch and throttle so she doesnt get so frustrated and quit?
