I use this Weekly Reading Challenge in my classroom throughout the year as a homework page. It encourages students to read at home in different ways. On Friday I have my students turn this in and depending on how many points they have earned they can either earn one prize (for a minimum of 250 points) or two prizes (for a maximum of 400 points). My students are OBSESSED with this and come in talking every morning about how they completed the reading challenge (and bonus challenge) from the night before.
The prizes I use are from the Oriental Trading Company.
