UFT child care providers who are working on their CDA credential began the day by sharing the projects they use in their programs, during a workshop at the Brooklyn Historical Society on Saturday, Dec. 3, 2016.

The museum gave each table colonial-era toys or tools to handle and discuss how best to use in their programs. Yvonne Best of the Bronx examines a washboard she said could double as a musical instrument.
