We're over the moon to report that two weeks ago, 7.5 million children and adults in more than 100 countries set a new World Record by taking part in the 'World's Biggest Lesson'.

As we reported on our blog in the run up to the event, the day was held to remind world leaders that 72 million children are denied a basic education.

We'd like to say a huge thank you to all the teachers and pupils who took part, especially to the hundreds of schools and an estimated quarter of a million children and adults in the UK.

To give you an idea of what went on in schools in the UK, we've posted some photos below, but there are many more over on Flickr.

And though the World's Biggest Lesson may be over for this year, there's still plenty of time to get involved with the campaign and keep the pressure on in the run up this year's G8 summit, where world leaders will continue to discuss progress on making education for all a reality.

You can still order a free schools pack with everything you need to take part, and help make sure world leaders keep their promises to provide primary education to all children by 2015.
