I make flashcards for students and use the rings to attach them. I love the colors. The students choose their color and can pick up their flashcards right away/
I bought these for my middle school kids. They use the colored binder rings to help organize each of their subjects at the end of each marking period. So each subject gets a different color ring. This helps lighten the load for them carrying their binders back and forth to school and at the same time keeps their papers together and keeps them from losing anything. This way when they go back to study for mid terms and finals they have everything all together and will not be missing anything important!
