How can I help my struggling child?

Hey y’all… so I feel like I’m failing a little bit. My oldest son who turned 4 in July of this year is in PreK 4. He goes to school 3 days a week and on Wednesday they get homework sent home… He struggles with writing his name without the tracing lines & a little bit with cutting w/ scissors. He’s gotten better with scissors but the writing he struggles with… Does anyone have any tips to help with making writing easier. I practice as much as I can and I’ve also ordered work books to help him but I was always the kid who STRUGGLED with homework and I find myself getting frustrated (stupid I know) so I try to breathe and to let him know he’s doing good it just takes practice and to never give up bc I don’t want him to struggle like I did but, if anyone has any tips or advice it would be greatly appreciated
