This project page has students fill out a reflection when done (p. 1) and includes sample completed project links, directions for accessing Scratch's tutorials, and a checklist for learner to follow and teacher to grade. This material follows the "Let's Dance Animation" tutorial on http://scratch.mit.edu, which is aimed at beginning programmers who have no/very limited prior experience. Duration to complete varies based on class length, computer abilities, and exposure to block-based programming. This lesson takes less time than some of the others.
Please ensure the tutorial is still live on the Scratch website before purchasing this material.
