Learn this move:
Start by coming in on an angle towards the net. As you get closer to the net bring the puck to your forehand, convincing the goaltender that you are going to shoot the puck. As you drag the goalie across the net you extend your arm, and stick towards the area you came from, easily sliding the puck into the net.
Remember that convincing the goalie with the shot is very important. You must sell the the shot and be able to drag the goaltender across the net, away from the area you actually wish to put the puck, which in this case is usually to your backhand.
