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 www.sendurl.co.uk. If you click the create new session button it will generate you a code. Send your class to www.sendurl.co.uk, they can enter the code, click the arrow button. You can then type/copy/paste any URL you want them to go to into the text box on your screen and it will pop up on their computer with no need to type. You can keep adding as many URLs as you like.
