I call this my School Work Rewards Chart that I use with my home schooling kids. There are 2 themed charts--princesses for girls, and ninja turtles for boys. I've also included a chart for each theme with a generic "Rewards Chart" title so you can use it for other types of rewards (not just school work completion) such as behavior, chores, classroom jobs, good-helper, etc.
The chart is organized with 4 generic weeks, with 5 days of school per week. At the end of the week, if the student has earned 5 stickers (or check marks, or however you decide), he/she earns a prize! You can simply print a new chart each month, or laminate them and use a vis-a-vis marker.
