Today, my mother took me to the market to buy food. There are so many dishes in the market! My mother and I walked and watched, and unconsciously came to the place where we bought mustard tuber. I said, "Mom, shall we buy a bag of mustard tuber?" Mother said, "All right! But you have to answer a math question. One yuan for four bags of mustard tuber and a few yuan for one bag? " I thought about it and said, "2 yuan 50 cents." Mother said, "Think again!" "oh! I thought for a moment and said, "It should be 25 cents." I said. My mother smiled and asked me how I worked it out. I said, "I took it apart and worked it out. Buy two bags for one yuan, fifty cents each, and then buy two bags for fifty cents, twenty-five cents each, which is equal to the price of four bags for one yuan. " "Mom said," You are so smart. You got it right. This package of mustard tuber is for you as a prize! ”？ Before I reflected, I always had a bad habit, that is, I couldn't sit still in class and always had to leave my position. I don't know how many times my mother has told me this habit, but I always turn a deaf ear and can't quit. Not long ago, with the help of my teacher and mother, I thought of a good way, that is, let the teacher record my performance in class every day. It really worked. I gradually got rid of this bad habit. But the teacher said that I still have a bad habit, that is, I like to interrupt in class, but I don't know why, I want to try to correct it, but I can't help but say it when I am excited in class. I made up my mind to get rid of this bad habit before the end of May, and let my teacher and mother watch my actions.
