Free Rice

Multi-tasking: "the performance of multiple tasks at one time." (Merriam-Webster)

This is exactly what students are doing when they practice vocabulary on freerice.com. This website allows students to practice vocabulary in Italian, Spanish, French, German, and English (other subjects are also available).  For every question that students get right, 10 grains of rice are donated to people in need. What could be better than that?

My Spanish professor in college used to assign us to do vocabulary practice on this website.  There are a variety of levels for each subject.  There are no specific topics within a subject to choose from, though.  Still, I think this is great practice and a great way to get extra-credit while doing something good for others.  You can also create groups on the website, so you can add your students into one group.

Here is the multi-subject link.  Choose which subject you would like to practice.  Then choose your level. Simple as that!
