We have just finished reading The Wizard of Oz as a serial and I managed to find an old battered copy of the Marvellous Land of Oz to read next as an afternoon serial. The grade 3 students working on the Oz theme have started tasks from my Wizard of Oz unit which I'll post soon. I also bought some great graphic novel sequels and prequels for Wizard of Oz ( some of them published by Marvel.There are also some great Wizard of Oz apps available for iPads.
PS- I've just notched up 9000 views for my blog. Thanks for having a look, I hope you find something you can use.
