Let's count to five in ASL!
All of these are with your hand out in front of you, and your palm facing toward you.
Hold up these fingers for each number:
1 - Index finger.
2 - Index finger and tall finger.
3 - Index finger, tall finger and thumb. (not ring finger!)
4 - Index finger, tall finger, ring finger and pinky.
5 - All five fingers.
