This is a great stand alone PowerPoint resource that is a great introduction to long division at a lower and middle elementary school level. Technically speaking, the language is all very clear and in big and easy to read text that isn't the least bit confusing, an important aspect to think about when dealing with kids of the target audience. There are many, many images that all have a purpose in representing what the text already said. One of the aspects that I especially liked about this StAIR was the way that integrated feedback was incorporated. Students are actually asked questions throughout the presentation. Interactive buttons on-screen would pop up, and the user would click on the answer they thought was correct. When they clicked correctly, they got a large cheer sound effect, which acts as somewhat of a novelty idea that gets kids into th learning by making the StAIR somewhat of a game and a learning resource. I thought that the layout and progression of the slides was excellent as well. Every slide had animations and sound effects that served as an interest capturer as well as not allowing kids to fly through the StAIR. Stopping kids from consistently pushing the forward button when they think they understand it and "forcing" the to review each slide for around 10 seconds is a great attention grabbing method. The only thing that I would maybe have added would have been a video of some sort to give students just 1 extra pedagogical methodology of getting across the information, but this is just a minor nit-pik. Also, a back button along with the provided forward button would have made navigating the slide show a little bit more advanced. This is a well done StAIR and I would definitely recommend it in an introduction to long division.
