If you are having your students write their names, maybe you can have them do 'rainbow writing' as they tracing over the letters of their name several times with various colors.
For your student of the week it occurred to me that you might have them choose the game, song or 'brain break' each day.
I found this page that has more suggestions (listed below) to consider:

Activity Ideas
--Child brings something special to share with the class – a possession, collection, or possibly a pet, if the school allows it.
--Child brings a favorite book to share. The teacher can read the book to the class, or the student can. For longer books just read a selection. Another idea is to allow the child to invite a grandparent or other special adult to read the book.
--Child brings in a special CD to share.
--Child puts a special object in a bag and leads the class (or helps the teacher lead) in a yes/no guessing game to guess what is inside.
--Child gets to eat lunch with a chosen friend in a special place in the room, such as the Class Library.
