0 second year, second grade

So the principal at my school decided I was smart enough for second grade!

As most of you know, I will be looping with my firsties to second. 

Same classroom. Same class. Different curriculum (aka first grade on steroids).

Since school starts in 18 days (YIKES!), I need to start gathering some second grade resources.

I would love to know about all second grade blogs, websites, etc.

If you have taught, or teach second grade, what are some of the favorite things you did?

Thanks in advance, you guys are seriously my best resources!
