One thing I have been doing for the last couple of years is having students keep track of the books they read in the hallway of our school.
Students write the title of a book they have read on a paper "book spine". These are piled on top of each other to form stacks for all to see. Having their books visible and to see their stack growing is motivating for many students.
Student Book Reviews
This year I started "allowing" students to write a book review on our white board easel and we put the easel at the beginning of our hallway.
This activity is optional, but many students really enjoy it. They love to see their writing on display and having others read their review. The best part is when another student will ask to read the book after reading the review.
What are some strategies you use to promote reading in your classroom?
