Hooda Math is an awesome site for math games, tutorials, worksheets and movies.
How to use Hooda: “Hooda Math can be used in a number of ways. Our online math games can be used for computer lab activities with/without our free math worksheets. Our math games can also be used with your interactive whiteboards, check out our SMARTboard Games page. Middle and Highschool students can do Math Movie projects with xtranormal.com and submit them to us for publication. A classroom teacher favorite is our free online math tool, Math Timed Tests that emails individual reports back to teachers and students.”
Hooda Math just about covers everything you need to help students learn new math skills and reinforce them. The students at my school loved using Hooda Math in Computer Lab last year. I have several Hooda Math games in my Brain Games LiveBinder. This find is via D. Crespo.
All in all Hooda sites are fantastic resources to use with students.
