Do you send home all graded papers once a week in a graded paper folder? If so, use this page as a way of keeping track that parents review the papers with their child. Simply staple it into the folder. You write the date the papers are sent home. There is a column for you to record how many papers are in the packet. (Upper grade students tend to remove the not-so-great papers!) The parents sign in the column provided. Easy as pie.
I've also included a copy of this signature sheet without the paper count column. In our school, we send home graded papers once a week. It's always on the same day, and the entire school follows the same process.
