The letter O is signed by curving all your fingers and touching them to your thumb, making the shape of the letter 'O' with your entire hand.
Teach your toddler the letter O sign when it is necessary to finger-spell some simple words - or the initials of objects, places, animals, or people's names. That way, your toddler slowly begins to associate the sign with the sound of the letter in a word or name.
This is a useful flash card taught best in conjunction with the other letters of the alphabet.
