The Letter "E"
To form the letter "E," straighten out all five of your fingers, as if you're giving a high five. Once your fingers are straight, take the tops of each of your fingers and bend them over at your joint, forming a bear claw-like shape.
The Letter "F"
To form the letter "F," take your thumb and your pointer finger and form a circle. With your three spare fingers, straighten and spread them out, forming an "O.K.- like" sign.
The Letter "G"
To form the letter "G," take your thumb and your pointer finger, and form a rectangle-like shape. While your two finger are forming the rectangle-like shape, keep your three spare fingers down, and pressed to your palm.
The Letter "H"
To form the letter "H," take your ring finger and your middle finger, and press them together. With your spare fingers (excluding your thumb), press them against your palm, and they will form a bump. While your two fingers are in that position, take your thumb, and rest it on the two fingers pressed against you palm. If you correctly formed the letter "H," it will ending up looking somewhat like a gun.
The Letter "I"
To form the letter "I," bend your three fingers (excluding your pinky finger) , and keep your thumb near the three others. Straighten your pinky finger.
