important things in my backpack

In my backpack, there are many important things I need to have for school. But i think these are the three most important things that I have to have to be prepared for everyday at school. The first important thing that I have in my backpack would be my pens because I need those to write and do all of my school work. The second most important thing would be all of my school work and homework so I can be ready for all of my classes. The last thing I think is important in my bag would be my phone in case of an emergency and I need to text my mom or brother about something.
