When I first started teaching many moons ago finding resources on the internet was quite a different process to what it is today.
There was a lot less commercialism, things were a great deal more disorganised and so on... I always remembered using a website with my kids called Jenny Eather's writing fun which just had great ideas for teachers and students about teaching different styles of writing. It was really easy to use, engaging for the kids and just made sense... It was great.
Anyhow, writing fun got bought out by a larger company and became a paid website which greatly reduced it's appeal.
But last week I was introduced to a very similar site to writing fun called literacyideas.com. It's completely free, broken down into different styles of writing and actually has a a load of great free content to downlaod or share on an interactive screen with your students.
I strongly recommned taking a look at literacyideas.com if you teach writing to primary / elementary students and would love to hear if you know of any other great sites similar to this.
