The Catan Dice Game comes with small marking pads to keep score, but you can get the pdf of the score sheet off the Catan website and print it out full size.
By laminating the pages with plastic (yes I know) I could mark the pages and then re-use them.
I did not want to use a plastic pen to mark them but I found a pencil to do the job - Staedtler Glasochrom.
