The Power Point StAIR is very neat in appearance. The StAIR effect was very effective starting with a simple problem and working to more complicated problems and bringing in the concept of the fact family. Students will enjoy participating in this activity. You included just the right amount of information on each slide and the quiz questions were great practice.
I am very impressed with the design, presentation and educational content of your StAIR. A very nice design style and appearance. The animations of text and graphics were very entertaining. Students will enjoy using the StAIR. The music and sound effects are great. The buttons and hyperlinks all work.
Consider narrating the text to help all learners. You may want to include on slide 11 a practice of how a student would input an answer.
