If the stock price goes up from $51 to $52, the option price might go up from $2.50 to $3.10. That’s a $.60 move for a $1 movement in the stock. So delta has increased from .50 to .60 ($3.10 - $2.50 = $.60) as the stock got further in-the-money. Gamma measures the change in an option's Delta, given a $1 move in the underlying security.
