Math or Gambling?

My husband took the week off and I’m not sure it was such a good idea. I went home to check on everyone and found my husband and nanny teaching the kids how to play Blackjack. I just stood there in disbelief and my husband said, “What? Its a math lesson.”

Then my 9 year old, without taking her eyes off the dealer said, “Hit me.” At least there is no money changing hands.
