Education.com of course has some fantastic stuff! I teach children with autism, so I am always looking for curriculum ideas and other things like that. I have several favorite websites for information like littlegiraffes and thevirtualvine. I have also found that Brainpop Jr. and Brainpop have a ton of great stuff that is aligned with most state standards. Good luck! On my youtube page I have several videos of how I organize my personal classroom.
I suggest www.PhillipRoyAcademy.com or www.PhillipRoy.com. I absolutely love their curricula and it's affordable and online. I would check them out. I use their pre-k online program with my daughter. It's a lot of fun and keeps her focus and attention, too. I hope this helps!
