When you first come up to a table, you have to buy in. So when you put your money on the table (and remember that you have to put the money on the table; you can't hand it to the dealer) the dealer will go "check change." And what they will do when they say "check change" is bring out the chips to give to you. They say "check change" so that the floor person can come over and look. In addition, sometimes when you're cashing a chip, the dealer will also say "check change", the floor person will come over, check it to make sure everything is done properly.
