We can't help you, no matter how big a font you use, until you give us something to start with -- namely YOUR best attempt to start on a solution to YOUR homework problem.
Ask your friend Google like synchronous+counter. He may come up with something that may help you. But of course your teacher may also do the same search. This is a very common assignment. And also an exercise in using Karnaugh map
