Download and print out this worksheet:
Fold it in half, and then fill in the case endings paradigm and the definite article paradigm, as well as the first six noun rules.
Then turn the page over, so the part you filled out is no longer visible, and do the same thing on the other half of the page.
If you are able to print this form double sided, then do so.
Continue to print and fill out the worksheet until you are confident that you have memorized these two paradigms and the three rules.
