A few months ago I wrote about this site in which you could go and take a look at the most creative classroom displays ever!
Well,they now have this new brand site which I absolutely love:http://usefulwiki.com/displays/
It’s a blog now,so it’s even better,it means now you can post your opinions or questions and give feedback to the administrator of this aswesome site.

I’m posting some other useful websites on classroom displays here 
I’m working on a maths display for division and multiplication and on some literacy displays for second graders. I’ll let you know how they turn out 
I’ll let you with some cool displays I think I might use for inspiration:(From Display Photos)
MATHS
I think this Maths Words display is so good! You know how difficult can be for children to get to know and make use of these terms! This would definetly help kids remember them.
The ladybug display is about division. What I like about it is that it’s interactive! Boys can play and divide with this display;it’s cute and practical!
LITERACY
Wh- questions! This is also sort of an interactive display,very useful!
The writing display is a good way to remind our kids to use these elements when needed. 
Goed dat je dit geplaatst hebt!. Heb het gelijk doorgestuurd naar een neef,hij was hiernaar opzoek! Mooie site trouwens!
i love it,thanks for the idea!
