One hand with the middle finger up, the other hand with three.
To sign "good morning class," you can sign "good" by touching your chin with the tips of your fingers and then bringing your hand forward in an arc. Then sign "morning" by tracing the outline of the sun in the sky with your dominant hand. Finally, sign "class" by using a classifier handshape to represent the group of students in front of you.
The way I was taught in my ASL class was put your hands in front of you, palms facing you left hand in front. Then move your right hand over your left without changing your palm placement.
First, make a thumbs up with your left hand. Then, make a gun with your right hand. Next, pretend to shoot your left thumb with the tip of the gun. (So that your knuckles are touching). From the front, it looks like a 14.
