I blogged about this back in October 2009 and posted on my Literacy wiki a couple of years ago. Telescopic text is a great way of showing students how to expand their sentences. The original Telescopic text starts off with a sentence, click on a shaded word to see how it expands.
You can now make your own Telescopic text, and/or you can also have an account where you can save them and return to them later.
These would work well as an IWB activity where groups of children can collaborate on one piece of writing. Or if you have access to several computers, students can be independently writing their own and sharing their different stories later, which could possibly be further edited.
Yesterday I was working with a teacher and we were thinking about different ways to make a student's reading experience more fun and interesting and then to link it into his writing. The following poem was part of the story she was going to use with him from a Junior Journal (Junior Journal 36, Dancing Bees by Lynette Bradley.) and it is perfect for enlarging and adding to.
So here is a tool that you should add to your 'Teacher Digital Toolkit'.
