How to use a textbook

In this lesson, Grant suggests four alternatives when the teacher decides the texbook is not appropiate

OMITTING: There´s nothing wrong with omitting lessons from textbooks. This is a kind of pick and choose approach to what´s in front of them. However if the teacher omits too many pages, the students may begin to wonder why they are using the book in the first place, espcecially if they have bought it themselves.
REPLACING:Grant´s second opinion is to REPLACE the textbook lesson with one of the teacher´s own. This has obvious advantages: the teacher´s own material probably interests him or her more than the textbook and it may welll be more appropiate for the students. If too much of the textbook is replaced, both, students and teacher may wonder if its worth bothering with it at all.
ADDITION: IF the lesson is rather boring, too controlled, or if it gives no chance for students to use what they are learning in a personal kind of way, the teacher may want to add activities and exercises which extend the student´s engagement with the language or topic. Addition is a good alternative since it uses the textbook's strength but marries them with the teacher's own skills and perceptions the class in front of him or her.
ADAPTATION:This is the final option for the teacher: to adapt what it is in the book. If reading texty in the textbook is dealt with in a boring or uncreative way, if an invitation  sequence is too predictable or if the teacher simply wants to deal with the material his or her way, he or she can adapt the lesson, using the same basic material, but doing it in his or her own style.
