Xtramath.org is an excellent no frills, instant feedback, free, math fact fluency practice. Your child should login until they are automatically logged out each day outside of school, at least 5 times a week. (About 6-15 minutes) This also uses Clever!
This website has support and information for our Math Expressions curriculum
Math Playground is one of my top math game sites. Don't be tricked by "Coolmath" check out Math Playground!
Here you will find some great math rap/video songs and some other educational videos such as study guides. Our students should be able to create their own math videos for our school.
