Angered by poor classroom conditions, students at Paul Éluard High School in a suburb of the capital were among the first to blockade their campus during an ongoing round of unrest.
Union members, parents, teachers and others took part in mass demonstrations around the country, backing student demands that the government invest more in schools.
Hundreds of schools will suspend some or all classes on Monday, the education minister said, as students protest conditions in the education system. Thousands of protesters have been arrested and hundreds of people injured.
