The other day, we went to "Happy Valley" to play. The adult entrance ticket price of Happy Valley is: 140 yuan; Half a ticket for children. While waiting in line to buy tickets, my mother asked me to calculate how many tickets we need to buy. I blurted out, "I want 700 yuan." My mother asked me in surprise how I calculated so fast. In fact, I think this is a synonym: four children's half tickets are equal to two adult tickets, plus three adult tickets are exactly five adult tickets, and five 140 tickets are exactly equal to 700 yuan. Mom praised me for being great!

One day, my mother and I went to buy floor tiles. My mother came to the tile shop and improvised a math problem for me: "haven't you learned to calculate the area?" I'll give you a math problem and see if you can answer it. "I confidently replied," what's the problem? Although you mentioned it, I am not afraid. " Mother said, "Our room should be tiled. This room is 7 meters long and 5 meters wide. Can you tell me how big the floor tile area should be? "I think: the floor of the room is rectangular, and the area is equal to the length times the width, so it is equal to 7×5=35 square meters. So I answered my mother loudly: "The area should be 35 square meters. "Mom was very happy, smiled and nodded, and bought a small gift to reward me on the way home.

Sunday, May 8, Sunny 1, Class 1 Yu Runjia.

On the way to school, I saw a shop open. There are two atmospheric flowers hanging on both sides of the shop. There are 12 big red flowers in the middle door, which are made of red silk. Very beautiful. On both sides of the building, from top to bottom, there are also 29 colored cloth strips with four big characters, "Business is booming". I calculated that 2 plus 12 plus 29 equals 43. I'm glad I can work out the formula of continuous addition.

Class 1 (4) of Badong National Experimental Primary School in Hubei Province is Xiang Xing Ning Zhuo.

Today, the teacher taught us the jigsaw puzzle, which consists of a parallelogram, a square and five triangles.

In our daily life, we can't do without the basic plane graphics in the puzzle, which can spell out interesting graphics, such as trees, houses, little girls, kittens and so on. As long as we study hard and love to operate, puzzles can be useful and interesting.
