IXL is a great math program that the 2nd and 3rd grade students have a subscription to. It is great to practice specific skills aligned to the second grade standards.
To log-in, have your child enter their username and password. Then click on level D and start practicing. The great thing about IXL is that you can push your thinking by practicing one level up (level E) or review material by practicing one level down (level C).
