I used these reading logs during RIGHT TO READ WEEK. They were a success for encouraging students to read at home. I used the 4-Day log for grades K-2 and the 7-Day log for grades 3-6.
Students take the log home and record the total minutes they read each day. They return it back to school signed by their parent and receive a reward. Possible incentives can be "Milky Ways", "Rocket Pops", "Moon Pies", and/or "Astronaut Ice Cream".
