With schools closed due to coronavirus, the BBC previously pledged to deliver the “biggest education offer in its history” for pupils.
Patricia Hidalgo, director of BBC children’s and education, said: “These extraordinary numbers prove that people continue to turn to the BBC in times of need.
“We’re thrilled to be supporting so many families and teachers across the UK with our curriculum based and edutainment content on air and online.”
Prime Minister Boris Johnson previously praised the BBC for its “fantastic initiative”.
