FreeRice.com is a website I’ve been using for about 10 years with my students. It’s a great way to study English vocabulary and grammar, in addition to learning about other subjects such as science, math, art, music, etc. The real bonus, however, is that every student who studies using their software is doing their part to feed the hungry. The company involved will donate 10 grains of rice for every correct answer.You’re welcome to use the school account or make your own account. It’s 100% free.
