How to distinguish the time when sophomore knows math?
The requirement of knowing time in the second day of junior high school is to be able to write time and minutes correctly. There are two ways of expression, one is text representation, and the other is spreadsheet representation. For example, 2: 15 is a text representation and 2: 15 is a spreadsheet representation. When you know the time, look at the hour hand first. When the hour hand passes, it is time, or: write a few words in front; Look at the minute hand. The minute hand is 5 points in the big grid and 1 minute in the small grid. When the minute hand points to several points, multiply by five points, and then write the number of minutes or: after the minute character.

In addition, when you finish the exercises, you should also look at whether to write the current time or how much time has passed, and do the questions flexibly.
