Schooling a greenie over jumps.

i would start with ground pole's first.
Lunge them or ride them over them, introduce them to it, when they are loose. it rather depends on how the horse react's to things, all horse's are different.
after you can get them to w/t/c over ground poles, you can suspend them alittle bit off the ground. but Just work slowely and at a comfortable pace.

Im sure someone can add to this.

hmm, there must be something to encourage her..
