This site could be used as an extra help for students. There are many different types of games such as jeopardy and basketball to help students have fun while still working on math problems. Each section of games deal with certain concepts covered in the classroom.
This game is a helpful tool to integrate into the classroom to help review multiplication. I have noticed that students are having trouble remembering their multiplication tables so this would be helpful to use if you have an extra 5 or 10 minutes at the end of a class period.
