My fingers are a bit stiff so I took to using fat pens & pencils because they ease the strain on gripping them. GS9 was just complaining about his fingers getting tired and sore during some of the timed drills, slowing him down. So, I'm going to get him some fat 'adult' pencils and have him try them. Have any of your kids tried the thicker pencils or extra fat grips on the pencils?
