Concept of one
From about 10 to 12 inches from your child’s face, show your right index finger pointing up, and say, “One.”
Bring down your right index finger into a fist position and bring your fifth finger pointing up and say, “One.” Pause for about three seconds, and say, “One” again.
Bring down the fifth finger to its original fist position.
Now bring up your right thumb pointing up and say, “One.” Pause for about 3 seconds and say “One” again.
You have demonstrated the concept of “One” three times using your index finger, fifth finger and thumb.
Repeat the same method and use your left index, fifth finger, and thumb.
