The town asked reporters to stay away to allow residents to grieve in private.
Church bells tolled 26 times in memory of the 20 children and six educators killed in the rampage.
Gov. Dannel P. Malloy asked for houses of worship around the state to ring their bells at 9:30 a.m., the moment that Adam Lanza shot his way into the school. Malloy also called for flags to be lowered to half-staff around the state.
Newtown officials have asked town residents to honor the victims through acts of service and kindness. At a joint appearance during the week in Newtown, some of the victims' families urged people to find ways to give back to their own communities.
"We ask that you consider performing an act of kindness, or volunteering with a charitable organization in your own local community," said JoAnn Bacon, who lost a daughter in the shooting. "We hope that some small measure of good may be returned to the world."
Lanza killed 20 children and six educators before taking his own life. He also killed his mother at the home they shared.
At the White House, President Barack Obama and First Lady Michelle paid tribute to the victims at a ceremony Saturday morning, lighting 26 candles representing the 20 children and six adults who lost their lives.
