In our class we use Saxon math. Every day we review the things we have already learned AND learn some new things. Each day we do the Class Practice page together as a class. Then the student does the back of the page, the Homeword B side, each night. On many nights the student also completes a speed drill. Weekends are for Family Fun so there will usually be no homeowrk given on Fridays.
Here is a link to some math activities from Saxon:
