This is an online quiz called Prime Numbers and Factors
There is a printable worksheet available for download here so you can take the quiz with pen and paper.
Find the numbers which are prime, and the prime factors of those which are not.
I made the background myself, so if you don't like it, gripe to me. ;-)
