you can use a simple counter like CD4029 and BCD to 7 segment decoder like CD4543.
the CD4029 is an up/down counter so you can have 1,2,3,...or 8,7,6,.....

Well, sub... I will not call you dumb. No one knows everything but you should seriously learn to help yourself a bit. It's just not fair to ask the members of this forum to do a net search for you when you could do it yourself so easily. Click the "Search" button on your browser, type something like "digital counting circuit", and press <ENTER>. Here's a good article that came up on the first page of my search on Yahoo:

I hope this will help you with your project and, if you've never used your browser's search feature before, that you will find it useful in the future.
