Freerice - Feed hungry people!

freerice.com  is a classic website to practise vocabulary. It is a non-profit website run by the United Nations World Food Programme, so every time you win a point, 20 grains of rice go to poor countries. But you can also practise German, French, Italian or Spanish, as well as other subjects, like Arts or Geography.
It is really addictive, but this time addiction isn't harmful!

Spellzone - spelling games

www.spellzone.com  is perfect to practise spelling. They focus on tricky letters, for example "ck" and give you a list to learn. Then, you can practise this list with four different games until you learn the words by heart. You can select from a great variety of word lists or simply try the list of the day.
You can do the same with vocabulary lists. Good luck!
