This reading logs helps the students track the books and number of pages they read at home for homework. It also asks that a parent/guardian signs their initials as confirmation that their child actually did the recorded amount of reading. It keeps all of this information organized on one sheet for the whole week, providing a record for both teachers and parents.
As an idea, I record the number of minutes each child reads each week throughout every semester. I can then use that data when it's time to do report cards.
