'The World's Largest Lesson' aims to teach children in over 100 countries about the new Sustainable Development Goals.
"Young people can help achieve the global goals by holding their leaders accountable for the promises they are making - and by holding themselves accountable for building a better future for everyone," said UNICEF Executive Director Anthony Lake.
The campaign is also supported by Indian NGOs The Akshaya Patra Foundation and Magic Bus.
Specially created lesson plans include an animated film by author and education expert Ken Robinson that introduces the Global Goals, and a downloadable comic book by Josh Elder and Karl Kesel.
"The World's Largest Lesson is a fantastic opportunity to tell all children, everywhere what the Global Goals are and how they can play their part to make sure they are achieved," said Richard Curtis, founder of the Global Goals campaign.
"As a father, I believe that all children should have access to good education and through this education they learn how to take care of their health.
"In order to achieve the best, they need to be fit and healthy. It enables children to push their extreme. These are fundamental rights that every child deserves hence I champion Goal 3 Good Health," the actor said in a statement.
The initiative aims to teach children in over 100 countries about the new 'Sustainable Development Goals'.
