The challenge

Now, more than ever, it’s so important to make people smile. That’s why we're challenging you to create an idea to help either people around you or the planet.

Could you build something to clean up your local area? Draw something brilliant to make someone lonely smile? Could you even build a machine to clean up polluted air?

Remember that we want your ideas to bring smiles to whoever see them.

The LEGO Group have put together some extra ideas on how to bring the BEST IDEA EVER challenge to your classroom, download them here.

Lucia has mobility issues and has trouble getting around the city. It’s always a big hassle.

Peter used to love going to school but has recently been picked on by other children.
