With the ability in Scratch 2 to create your own custom blocks, I have put together a tutorial on how to implement recursion in Scratch 2. The tutorial comes in the form of a post on my blog. The link for the tutorial is http://philcurnow.wordpress.com/2013/07/27/recursion-in-scratch-2/ Feel free to use the information in any way you like. I'm happy for you to post comments/questions on my blog, which I will respond to. Alternatively you can contact me on Twitter at @pcurnow.
Please find the resource uploaded here http://scratched.gse.harvard.edu/resources/recursion-memoization.
