Place a small tile or similar on the ground about 1.5metres from last board, make sure it is in the middle. Sit your dog up close to the first board, stay your dog, place a small yummy treat on the tile, go to your correct position and direct the dog over the jump when its head goes down to the tile, click and finish. Build it up from that, you will not need food, and you will not need the tile. I say the word "mark" instead of over.
