Break the problem down into smaller problems. You might start with a counter that counts from 0 to 5 and then starts back at 0 again. Get that designed and tested. Then add in the ability to pause it using a single start/stop push button. Then add in the ability to force it back to zero. Then extend it from 0-5 to 00-59. Or do these things in a different order as makes sense to you.

But in any event YOU need to show YOUR best attempt to solve YOUR homework.
