Here is my advise, it worked for me. (I tried to keep it in order, but I don’t know much from K-3)
1) Get a notebook for each class (for grades 4th through college). Take notes to make sure you are not day dreaming. My teachers would ask me, sometimes were they left off.
2) I know this sounds strange, but also worked. I put my books, assignment notepad/planner (on my right side), put homework and the notebook should be open, in the center, with homework on top, unless you are reading of course. Seeing my books helped remind me what class I was in, but only for that class,
3) At the end of class cheek with the teacher to make sure you wrote the assignment down correctly. I wrote the wrong assignment down many times.
4) My folder had different places for my homework and other things. My left side was meant for old papers, right side had homework on top and past homework that may be used for tests.
5) I would talk to your teacher and explain that you are having trouble focusing in class. Are you sitting in front of the class? For me sitting was important. I tend to talk in the back or gaze out the window. The teacher has full view of you so he or she will nip that in the butt. Get your parents involved too. You might have to be put on meds too.
Good Luck!REPORT ABUSE
