In the first grade math class, the teacher pointed to the watch and asked: “My classmates, what time are you looking at now?” “More at 7 o’clock.” Say? “” About 7 o’clock. “Then, the teacher will be the minute hand to the left tune, asked:” What time is it? “” Almost 7 o’clock. “” About 7:00. “Then a student suddenly said: ” wrong, “more than 7:00 ” is about 7:00, “less than 7 points ” should say about 7 Point. “The teacher’s speech was overwhelmed by the student’s statement ...
