About the Book

In this amazing story, neighborhood kids turn a barren field into a town with nothing but rocks and their imaginations.

The Cannon Cardboard City Challenge

We are super excited about our cardboard city challenge! Every year we celebrate creativity by having a cardboard challenge. Cardboard challenges across the nation are modeled after the creativity of one boy who created his own arcade out of cardboard. This year, each Cannon grade level will build a different part of the city out of cardboard and then we will set our city up in the Learning Commons for everyone to visit and enjoy.
