A fourth-grade math teacher at the Academy of International Studies in Danbury has been named Danbury Public School's Teacher of the Year.  Matthew Calvanese says he wants students to know that math is for everyone, even if it doesn't come easily for them.  He asks students to write down how they feel about the subject at the beginning of the year. By the end of the year, Calvanese says most of the negative feelings have waned and students find they enjoy math.  Calvanese has been teaching in the district at AIS since 2010, was a substitute for a year before that and did his student teaching in Danbury. He earned a bachelor’s degree in elementary education/psychology from Western Connecticut State University, a master’s in educational leadership from Quinnipiac University and a sixth-year certificate also in educational leadership from UConn.
