The 20-year-old global education campaigner made the suggestion at a meeting with Acting President Yemi Osinbajo at the presidential villa in Abuja.
Nigeria has some 10.5 million children out of school -- the most in the world -- and 60 per cent of them are girls, according to the UN children's fund, Unicef.

"The federal government, state government and local government should all be united for this. Secondly, the spending should be made public and thirdly, the Child Rights Act should be implemented in all states."
Yousafzai said there was a "positive response" to the suggestion from Osinbajo, who has been standing in for President Muhammadu Buhari since he left on open-ended medical leave in early May.
Yousafzai, who was awarded the Nobel peace prize in 2014, joined politicians, celebrities and campaigners from around the world to support the online #BringBackOurGirls movement to demand their release.
On a previous visit to Nigeria in July 2014, she urged the then-president Goodluck Jonathan to meet the girls' parents.
On the first anniversary, she called the missing girls "my brave sisters" and wrote in an open letter that she could not wait to meet and hug them. "You are my heroes," she said.
Yousafzai said she was "very happy" to see some of the girls, who are staying at a government-run facility in Abuja.
"I'm really excited to see them going back to their homes and to their families and continuing their education," she added.
"But I hope the other girls who are still under abduction of Boko Haram are released.
