My images won't upload, so forgive my terrible symbol images.
Set out a jump, the block should be under the letter B. Then set up a jump at E. In the centre (X) put out a trot pole. Go large, avoiding the jumps. At A, trot a circle to get your horse listening. Trot him over the pole. Then trot over the B jump. Then the E one. It's a good way to practice with courses and a very simple excerize. When your comfortable, put jumps up at A and C.
A Good control excerize is to set up a square with trotting poles. Trot through it so your horse is happy. Walk him over it. Halt in the middle. Try again and again at a trot. It will be quite hard, but it's a good way to get him listening.
