The Book Sale is the major fundraiser for the school and is a great display of team work, school spirit, and a passion for books! The funds raised from this annual event are a major part of the School Council annual budget and benefit every student at the school. At least 5% of the proceeds will go to other schools or charities that benefit children. Parents will be asked to volunteer for two shifts during the set up and sale, this request and electronic sign up will be sent soon- keep an eye out -the best shifts go early!

The book sale was launched by parents of First Avenue School students as a fundraiser in 1983. Children were encouraged to ask their families and neighbours for used books, and classes with high participation won prizes like a pizza lunch. One volunteer sewed a large canvas sign to advertise the sale. It was a winning formula that lives on in much the same way to this day, albeit in a new location, following the move of the local French Immersion program to Mutchmor in the 2015-16 school year.

It is traditional during book collection time for each class's books to be tallied and the counts to be displayed in the form of an enormous bar graph in the school hallway. The powerful incentive of a pizza lunch continues to be offered as a prize to the class that collects the most books, along with a prize from the Glebe Neighborhood Activities Group.
