Looking for a novel way to motivate your students? Want to make learners more aware of the work of the United Nations? You can do both by introducing students to Free Rice. On this innovative site, students can answer trivia questions, review math facts, and learn new vocabulary words while donating rice through the World Food Program with each correct answer. This is a unique way to prepare students for a test or a fun “sponge” activity for the last few minutes of class.
