I usually don't do homework this way, but since this is the week before Christmas Break, this made more sense. For homework, I want students to read for at least 20 minutes each night. I also want students to practice memorizing their multiplication tables. On Friday, students will take another timed quiz. The class' goal is to show you growth in the memorization of their multiplication tables by the time Student-led Conferences come around in February.
I would focus on one number each night and have students use http://www.multiplication.com/. After students play a few games, they should go to the "Auto-scored Quizzes" tab at the top of the multiplication.com page (http://www.multiplication.com/quiz/multiplication-self-correcting-quizzes). They can do further work on memorizing their tables and get immediate feedback.
