That is such a perversion of the purpose of 100 book challenge,which is to get kids to practice and enjoy reading. Our school has 100 book challenge for 1st through 3rd grade, which combine some reading time at school plus homework reading time. In fact, the teachers encouraged the students to get books from the school library and the public library and through purchase as there is a limit to how many basekts/books the school can provide and some kids/parents don't have the resources.

This is an argument that I would pursue. Were it not for the extensive collection of 3rd to 5th grade books that DS' 1st grade teacher (who previously taught 3rd grade) kept in the room and permitted access after the first few weeks of school, my DS might well have continued to get into trouble after he finished his work early.
