The Charles River Conservancy is excited to partner with MathTalk, a Cambridge-based organization, to bring a MathTrail art installation that introduces early intervention math concepts to the Magazine Beach Footbridge. The project has been developed by a team of parents, teachers, researchers, organizers, children’ media producers, designers, artists, game developers, entrepreneurs, CRC staff members, and kids and adults from the Cambridgeport community who came together to turn stories, public art and augmented reality into experiences that will inspire parents and children to explore math literacy together.

The MathTrail enhances natural educational resources locally and encourages safe travel over Memorial Drive to and from the Charles River Reservation. The transformative project introduces playful math opportunities to Magazine Beach that interact with the environment, including a gigantic number line, animal counting footprints, and access to a free digital learning app, Measure! Everything! Set along the Charles River, this interactive installation connects youth to their environment through free math play, and encourages youth and adults to interact with their local parks in meaningful ways. Community designers, teachers, parents, and children were instrumental in developing this work.

Invitation to visit the MathTalk installation at the Magazine Beach Footbridge. Invitation includes an image of the Charles River, and illustrations of children smiling.

The Magazine Beach MathTrail is open to enjoy. Visit and explore the MathTrail at Magazine Beach Park at 719 Memorial Drive in Cambridge.

We are excited to learn alongside the community and encourage you to join us in figuring out how many footsteps it takes to cross the Magazine Beach Footbridge! The MathTrail will be available to explore through Fall 2021.
