To sign wallet, with hands flat and facing toward your body, have all fingertips meet in the middle, steepling your fingers but horizontally so that they face outward, not upward. Then open and close both hands a couple of times, as if opening and closing a wallet or billfold.
Teach your toddler the wallet sign when he or she begins to be curious about money transactions.
Teach this sign along with the other flash cards pertaining to money transactions. Many toddlers love having their own wallet or purse for their coins.
