Click on the link to take you to the Brain Pop site. You may have to login, using the free 30 day account trial that your numeracy rep provided for you. If you forgot to sign up, you can use the login of another teacher in your school that did sign up.
Again, not exactly math related, but the more you use Brain Pop, the more you'll come to discover the advantages of the program. And, as those at Brain Pop say, "The more you know, the more you know."
