RIO DE JANEIRO, BRAZIL - Two weeks after Claudia's first day of school last March, she was already not allowed to attend - the school was closed due to the coronavirus pandemic. But that wasn't so bad for the first-grader from Uruguay: she learned the alphabet via audio tutorials. She enjoyed digital math lessons so much that she solved extra problems.
Video conferences three times a week helped her get to know her teachers and classmates better. And guided by her physical education teacher, Claudia, seven, completed gymnastics exercises in her room.
Claudia is not a wealthy private student . . .
