It is really important to be paying attention in class. Sometimes when you are at home and u are doing your homework and u dont get it, it may be because you didnt pay attention in class and yoou will not know how to do your homework because you didnt pay attention to what the teacher was saying. it is always important to pay attention because if you dont your grades and really drop down.If I want a better grade for my math class I can play attention to more about what the teacher is saying
