Also present in Dakar was global singing star Rihanna who vowed on Friday she would "never stop fighting" to get millions of children back in school.
Speaking at the event, Rihanna said while tremendous progress has been made, there's still a long way to go, and the fight isn't over until every boy and every girl in the world has access to education.
Macron and Rihanna previously met in Paris last summer, where the two discussed education and her charitable foundation to promote education worldwide.
Rihanna also took to Twitter to implore world leaders to invest in public education.
He promised 200 million euros for the fund, sharply upping France's earlier offer, and urged others to pitch in toward the 3.1 billion euro overall goal.More news: GM US sales trail estimates

It is not the first time the young French leader and the singer of "Umbrella" fame have met: she visited the Elysee Palace in July after tweeting him on the same issue.
Rihanna continues to be an advocate for education around the world.
The singer past year appealed to Macron on Twitter to contribute to her efforts to fund education in developing countries, notably in conflict and crisis areas.
Macron has visited Africa six times already in his nine months as president, spending time in several former French colonies and reaffirming support for the Barkhane counter-terror force rooting out jihadists across the Sahel region.
President Akufo-Addo left the country in the early hours of yesterday for a return trip to Senegal.
Jeune Afrique quotes Senegal's interior minister as saying he will ensure the safety of all conference attendees. She reportedly travelled on the same South African Airways flight as World Bank President Jim Yong Kim.
