The following is a website game I learned about that I would IMMEDIATELY take back and use in my classroom if I were still teaching. It's called Kahoot.
Kahoot would be a great way to review for a test or practice fluency with basic math facts. At the end of the quiz, the teacher can print out a results page to see which questions were missed most, letting her know what she needs to clear up or reteach.
