Do your students not read at home? Do their parents not understand that knowing your math facts is imperative to success in mathematics? By assigning that students read and do math facts, you not only teach them that these things are important, but it lets their parents know it is important as well. I have used the HRF/MFF folder for the past 7 years in my classroom. There are other teachers in my school that use it as well. It is a simple and quick way to keep track of these assignments.
