Like all parents, I sometimes struggle with my child at homework time. My first grader's regular math exercises include a variety of activities, including multiple choice questions. He often bubbles whatever answer strikes his fancy in hopes that I won't notice or check his work. In anticipation of this, I now cover the answer options on his worksheet with mini post-it's and ask him to work out the answer before he can lift up the stickies and fill in the bubbles. (Can you tell I'm the teacher mother?) This week, he was particularly frustrated with my strategy. It was 4:00. He wanted to go over to his friend's house to play. He gave me that wide-eyed, Puss in Boots, imploring gaze and argued, "But Mom, sometimes bubbles help me. Can't you just tell me the answer?" Now there's a question I have fielded before. I gave him my stock answer: "I'll tell you the right answer, honey. But then you have to tell me why it's right."
