France has already closed 81 schools and 2,100 classes due to Covid-19 cases since the start of the school term this month, according to education minister Jean-Michel Blanquer.
In addition, Blanquer said about 1,200 new infections among students had been recorded since last week.
"These are numbers that remain low," Blanquer told French TV channel LCI on Wednesday.
Blanquer said the 81 closed schools represented only 0.13% of total schools in the country.
France recorded more than 10,000 new virus cases for the first time since the start of the pandemic over the weekend.
This week, the cities of Marseille and Bordeaux have tightened coronavirus restrictions on public gatherings in a bid to curb rising numbers of cases.
The move comes after French Prime Minister Jean Castex addressed the nation on Friday, asking local authorities to present new measures and emphasizing that Marseille, Bordeaux and the Guadeloupe were particularly affected areas.
