Would like to let you know about a great new site Primary Teachers Network: www.primaryteachersnetwork.ning.com
.... please also read Elementary Teachers Network :)... that's right... just for the teachers who deal with the little guys!
To get straight to the point, the differentiating factors are:
1) Huge bank of interactive white board activities for maths, science, games and english (5000+ and growing)
2) Quality blog with a great array of modern educational tools and ideas.
We are hoping to have some more quality input from the worldwide community to build some more depth in the content/ posts.
