The most brilliant teacher I ever knew, when my kids were little, was Ms. Palacio. She strongly believed that the MOST CRUCIAL lesson for young children was learning to be patient about gratification. She would give them little treats and little toys on some mornings, and instruct them to keep them inside their desks, until the end of the day. And if they went ALL DAY, without opening the gift, or tasting the treat, then they had the chance to have another, even better present at the end of class. Early in the year, very few students could wait. But then they would see a few classmates getting a better bigger reward for waiting. By the end of the year ALL OF HER STUDENTS were capable of being handed a candy or a wrapped toy, and setting it on top of their desks, and waiting the entire day to taste it or open it. I consider that one of the greatest gifts that she taught my 2 kids!
