Math diary 100 Unit 4 Words in Volume II of Grade Four This morning, I started the "launching ceremony" of reviewing, practicing and strengthening mathematics according to the "holiday plan" my father asked me to write!
I thought it was a little difficult at first, but it became easier and easier, and I thought math was so interesting! For example:
There is a five-digit number, the lowest digit is 8, the highest digit is 3, one digit is twice the tenth digit, and the sum of the first three digits and the last three digits is 19. What is this five-digit number?
Answer:
First calculate the highest and lowest digits of this five-digit number, then calculate the ten-digit number 8÷2=4, then calculate 8+4 =1219-12 = 7, and finally calculate 3+7 =1019.
I didn't like math before. It was boring. Now I think math is so simple and interesting! You will love math!

Composition in Unit 4, Volume 2, Grade 4. A real thing.
There is a cruel photo on page 19 of our textbook. This photo was taken by a reporter when the Japanese invaders bombed Shanghai South Railway Station on August 28th, 937. There is a child in this photo. Why is the child crying? Maybe his parents are going back to their hometown, but when the explosion happened, the train suddenly rang and his parents disappeared, leaving only the children crying here!
Then where are his parents? Perhaps this child's parents have lost their precious lives by the Japanese, but it is unbelievable how many people lost their precious lives in War of Resistance against Japanese Aggression at that time. But what might have happened then? At that time, parents may have to leave this place and go back to their hometown by train. Maybe they don't know that danger is facing them and approaching them. But when the Japanese invaders bombed Shanghai South Railway Station, his parents had already left this world. Leave the little boy, but the little boy will never see his parents again
What is the future fate of this lonely little boy? Maybe after the war, the little boy will be adopted by good people, maybe by the Japanese, or when he grows up, he will avenge his parents, his country and his people.
This series of problems appeared in my mind, and I knew they had been solved! Students let us fight against Japan together and prevent the enemy from bullying our country. We should maintain peace, and let peace stay between each of us forever!
