How to organize binders for a block schedule?

I am currently starting my third year of high school. I have a block schedule which means that I have 6 classes. Mondays and Wednesdays I have classes 1, 2, and 3. Tuesdays and Thursdays I have classes 4, 5, and 6. And on Fridays I have all of my classes. Is there a system of organization I could use for this? I feel like it would be very heavy to bring all of my binders on Friday. Thank you!
