1000 book challenge

In January I challenged my students to read 1000 books by the end of the year. This was a big challenge for them, but we have been doing well. For each book the students read they must fill out a book review sheet and have a parent sign it to prove they really read the book. My students have been working hard (some a lot harder than others...) and today they reached 410 books! I am so proud of them! But I just don't know if they will make the 1000 by the middle of May....
