Do you have technology in your classroom?
I have been using my old iphone and this small voice recorder (here). When they do their Daily 5 work (or any writing) they can record themselves reading it. I really like how they can play it back and listen to their voices. I have many students who don't check over their work before handing it in, and recording their voices makes them read their work again. They also use the recorders to read poems and songs that we have done as a class.
The iphone and voice recorder are both (very) expensive items for grade 2 students to be using though. Although they are able to use both easily, I do get worried about them getting dropped/broken.
I'd love to hear what you use and enjoy in your classrooms!!
