Recently we have been doing a lot of topic/literacy lessons that need the children to find information from several websites. It's hard enough getting them to type one URL in at times, let alone 3 or 4; especially when the focus of the lesson isn't their typing skills.
With that in mind, I went away and built http://www.sendurl.co.uk. As a teacher, if you click the create new session button it will generate you a code at the top. If you then send your class to http://www.sendurl.co.uk, they can enter the code into the text box, click the arrow button and they are locked in. You can then type/copy/paste any URL you want them to go to into the text box on your screen and within 30 seconds it will pop up on their laptop/netbook/computer with no need to type. You can keep adding as many URLs as you like and they will pop up one after the other.
Hopefully some of you might find this useful, if you do could you let me know and more importantly let your friends know!
