Okay, so when you go to school, you learn lots of new things from your teacher. And sometimes, your teacher wants to know if you understood what you learned. So, they give you some work to do at home, and we call it "homework."
Now, when you do your homework, you should follow some rules so that your teacher knows that you did your work right. That set of rules is called the "homework convention." It tells you how to write your name, how to label your papers, and how to organize your work so that it's clear and easy to understand.
For example, your homework convention might say that you need to write your name on the top right corner of the paper, followed by the date, and the subject you're doing homework in. Then, you need to number your problems or questions and write your answers below them. Sometimes, you might even have to draw pictures to explain your answers.
Following the homework convention helps you learn good habits for organizing and presenting your work, which will be useful when you grow up and have to do more complicated things. And, it helps your teacher understand what you're trying to say or do, so they can guide you better if you need help.
So, always remember to follow the homework convention and do your best work!
