standard_description: Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 3^(2) × 3^(–5) = 3^(–3) = 1/3^(3) = 1/27.
problem_activity: Narrative
The purpose of this Notice and Wonder is to elicit different questions from students about a story to prepare them for writing their own questions for a math story in an upcoming activity. Although students may notice and wonder many things, the most important discussion point will be the types of mathematical questions that can be asked about the story.
