You’re right Terry! Many students would do it that way. If our learning goal however, was to help students develop a quadratic model (or algebraic representation) of this pattern then we’d want to help with generalizing. We often have students focus on the images in this example and ask “what would picture 10 look like”, “what would 17 look like?” “what would figure n look like?” “can you draw a diagram to show the shape?”
