I use this binder to help keep my units organized for teaching. It is very easy to organize and use. The one push button to open the rings is one of my favorite things and makes using it very easy.
I use these binders daily for my High School Classes. I select a different color for each one of my classes and ask students to get matching color. The transparent slip on front of the binder is home for lesson timeline making it easy to refer to when needed. (Students often ask "what are we doing today") The awesome non-slip surface on binder reassures me of a firm grip when I reach out for it. The bright bold colors are excellent choices for students. And of course the D-ring makes it so much easier to organize the handouts for class. Although I do not demand my students to get these binders I highly recommend that they invest in getting them.
My son went through 3 binders and this one was the last one I bought it is so study even he can't seem to destroy it. It has survived the school locker the football locker and a lot of books piled on it. It's a little pricy but well worth it! I'm guessing it will be a hand-me-down for his brother.
