BERLIN, GERMANY - MAY 04: A sixth grader wears a protective face mask and gloves as he attends class for the first time since March at the GutsMuths Grundschule elementary school during the novel coronavirus crisis on May 4, 2020 in Berlin, Germany. Across Germany tenth graders began returning to school last week and elementary school pupils are returning this week in cautious steps to reopen schools that have been closed since March as authorities lift lockdown measures that had been imposed to stem the spread of the virus.
