On Friday, March 20th, 2020, the weather was fine.

There is a square clock in my house, my mother said. There are three hands running on the clock face. They are hour hand, minute hand and second hand. The shortest is the hour hand, which runs the slowest. It runs 1 hour. Followed by the minute hand, it runs the second fastest, it runs the big grid for 5 minutes; The longest is the second hand. It runs so fast! One lap is 60 seconds. I like the minute hand and the second hand best, because it takes 1 minute for the minute hand to walk a square and 60 minutes for a circle, which is 1 hour. The second hand "ticks" is one second, and 60 ticks is 1 minute. They always remind us to cherish every minute. Look carefully, there are 12 big squares on the clock face, each big square has 5 small squares, and a * * * has 60 small squares. The math on the clock face is really interesting!

It will be cloudy on Sunday, February 2, 2020.

When I was doing my homework today, I came across an interesting topic: "Xiao Li went fishing. How many fish did he catch? " I couldn't figure it out for a long time, so I began to draw a picture in my notebook. Finally, I found: go to the "6" on the U-turn and leave "0"; And remove the tail of "9" and half of "8", leaving "0". I was so happy to find this "secret" that I wrote the answer in my notebook: 0. There is so much fun in mathematics. I like learning math very much.
