Big Backyard is a series of nature walks around the Fiske school and adjacent lands that enhances the existing science and social studies curriculum in each grade.  BBY walks emphasize observation, learning to ask good questions, problem solving, and respect for the natural environment – plus, they are a lot of fun!

BBY walks take place during the school day. The theme of each walk is coordinated with the Massachusetts Curriculum Frameworks to support what your child is learning in the classroom. The success of the program depends on parent volunteers.  To get involved, please contact the Fiske PTO at and look out for communications from your classroom Teacher and Room Parent(s) announcing BBY dates and requesting volunteers.
