Freerice.com was set up by the World Food Programme in 2007 in order to help provide food for those most in need around the world. Pick a quiz subject such as ‘English Vocabulary’ and match up words with synonyms. For every correct match, you donate 10 grains of rice to the charity. The longer you play, the more difficult the words get, but the longer you play, the more rice you can donate!
The website has expanded over the years and not only can you improve your English vocabulary and grammar, but you can also test your knowledge of other subjects like world geography or learn some words in a new language. Maybe you’ll even be inspired to start a new foreign language class. Have a try, you don’t need to sign up, you can just play. But be warned, it can be addictive!
