[Michlib-l] Summer Reading Question

Hello Everyone, I'm just starting out as a Youth Librarian and taking over working on a summer program that has already been somewhat laid out. I am working on the summer reading guidelines for kids. I am wondering what you do for the 3rd grade and up kids. Do you count pages read or minutes read? I'm debating between the two, but wanted to get other's opinions. Do you allow audiobooks to count as reading time? Thanks so much, Kristin Hammond Young People's Librarian Comstock Township Library
