So my first and second grade students set reading goals for the year in September. They pick a book they would like to be reading by June. We then do some additional intermediate goal setting throughout the year. Each month students track their minutes read outside of school and we do some basic data crunching in math class. We then do some reflective work on the student's effort into becoming better readers. We try to tie in the amount their reading at home to their progress in fluency.
Then in June we take a picture of them reading a book (if they met their goal, it is the book they chose for their goal.) I then use that picture in a summer reading document to send home explaining how they set a goal and met it. On that document I also have students list books, series of books, and topics they would like to read or learn about that summer.
What did you do to try and engage your students with summer reading?
