How I Use It
I use it as an option for students who have completed other work on the computer. I have also used it as an assignment in which students must write down words, meanings and examples for words they miss to keep them from randomly clicking or changing the level to something higher than they can manage.
Students enjoy earning rice, and they like that the rice they earn symbolizes a donation to the World Food Programme. We mainly use the English Vocabulary and Grammar sections, though some students choose to explore other subjects on their own time. It does get repetitive after a while, but most students enjoy using it to practice vocabulary from time to time.
