Hi Gisele, chances are that what you meant is "a guided study binder". It could be a guided Math binder. But then, with several pages, lots of pages.
Or perhaps, if you refer to only some "pages" handed to students, then it could be called "lesson sheets" (and then, they could be organized in a binder afterwards).
You can call them "handouts" or "guided reading worksheets" too.https://www.teacherspayteachers.com/Pro ... 101-640207
Let´s wait for more comments now.
