MPs went back into the classroom in the Huddersfield area.
They were there to highlight what they said was a lack of cash for education.
The MPs said £3bn - the amount Britons fork out in parking tickets each year - would give every child around the world an education.
Instead, 100m youngsters miss out on teaching because they are too poor or schools do not even exist in their areas.
To highlight the children's plight, Kirklees MPs Barry Sheerman, Kali Mountford and Mike Wood yesterday joined more than 400 Parliamentary colleagues in going back to class and talking about the importance of schooling.
Their action was part of the Global Campaign for Education Week of Action.
While Mr Sheerman met pupils of Moldgreen Community School and Crosland Moor Junior School. Ms Mountford went to see youngsters at Marsden and Meltham junior schools.
Batley and Spen MP Mr Wood had a busy day, visiting Batley Boys' High School, Mill Lane Junior and Infant School at Hanging Heaton and Birkenshaw Middle School.
During her visit to Marsden, Ms Mountford, who grew up and was educated in Crewe, said the importance of a good education could not be overstated.
"It is at this age that the foundations are set for people's ambitions and aspirations," she said.
"One of the keys for economic development around the world is education of children.
"If people are to have the same chances they need at least the very basic skills of reading and writing," the MP added.
Mr Sheerman said: "I spend my life going to schools as chairman of the Commons Education Committee. But this is special.
"The question is about what we are doing for education for children all around the world.
He reminded youngsters: "In England - and Huddersfield - not so many years ago children were forced to go to work."
He added of his visits to the pupils: "I have been putting over the fact there's a tremendous challenge in Africa and elsewhere."
Mrs Tina Blackaby, head at Crosland Moor Junior, said: "It is important for our young people to realise the importance of education and the implication of a life without the chance to learn."
She said the "back to school day" was a chance to connect children with democracy.
