Free Back to School Printable Book
Heather at Golden Expresssions Blog has a Free Back to School Book Printable which would be cool keepsake.
I love this because you can add their photos along with their writing samples of their favorite things and memories for each grade. This would be cool to have to look back on when they graduate from high school.
Be sure to check out our First Day of School Printables for that perfect photo opportunity, too!
