It seems to me that text structure questions come up an awful lot on standardized tests. I prepare my students with these bookmarks. Students use them to identify the text structure in their book (or a stack of books that I dump on their group’s table during whole class activities).
Print, cut apart, and give each student or group their own set. Laminate for longer life and reuse again and again!
Make it a game! Students love the challenge of finding one of each type of structure.
