BRYAN EATON/Staff photo. Zero the Hero counts to 100 by 10's with kindergartners in each class, here, Sherry Herzig's, after arriving to the Bresnahan School by police escort for the 100th day of school. The caped math super hero goes to each kindergarten class once a week to get students excited about numbers. Zero, a.k.a. Rob Ouellette, is hanging up his cape after 16 years or volunteering his time in the role.
