I found the Post-It Brand Tape Flags an excellent and inexpensive way to have students reach information in their textbooks quickly and easily with minimum difficulty. The flags can be moved daily as they progress in their textbooks and do not damage the print of the book. Students can use one flag for nearly the entire year and with the cost of $1.37, it doesn't break the bank. The students enjoy moving the flags and also feel privileged to have their books marked like their teacher's. You can also write in pen or pencil on the flag to specifically identify the section of the book, like the index, answers, glossary, etc. I also find them handy in my grade book, eliminating those troublesome paper clips I used to use to mark each different class that I teach.
