I'm looking for some quality educational websites, so please share yours and tell me what you like most about these sites. I am especially looking for those that center around reading, the parts of speech, grammar, etc. I am interested in websites for 4th grade and up.

Thank you !!!

Answer 1

I have suggested www.starfall.com to my younger readers - meaning kindergarten, 1st and 2nd.  

Answer 2

I'm a teacher in the UK so not sure if material will be transferable but www.primaryresources.co.uk is really good over here
