Our 3rd grade class does homework packets. Students receive their homework packet on Monday each week containing their assignments for the whole week. I do this so that students can work at their own pace. Homework packets are normally due on Friday. However, if we do not have school on Friday, then it is due on the last day of the school week. If students do not turn their homework packet in on time, they need to turn it in on the next school day. I also assign students to read for at least 20 minutes each night. I will post a list of what is included in the homework packet each week on the school's homework page.
The only other additional homework from my subjects would be if a student does not complete an assignment in class. Each day students have a specific amount of time to complete assignments. Many assignments are done as a class, in groups, or partially as a class so most classwork should be completed in school if students are working productively.
