One day, I learned the lesson of area. No matter how carefully the teacher explained it, I was not very clear, and even I made several mistakes in my homework. I want my classmates to tell me about it, but I'm not willing to. I was depressed all morning.

When I came home from school, I told my father about it. Dad told me to take out my math book, turn to the area lesson and look at my exercises. Explain it to me meaningfully. From my father's words, I finally understand what area means.

The next day, the regional test began. I walked into the classroom with confidence. After the test paper was handed out, I was not nervous at all. It will be finished soon. I was in high spirits when the teacher announced the exam results. Because I got a good score-98 points!

I said silently in my heart, "Thank you, Dad."
