problem_activity: Narrative
The purpose of this How Many Do You See is for students to subitize or use grouping strategies to describe the images they see. The synthesis highlights that the images show 1 more and 1 less than the initial image. When students use the dot images to subitize, they look for and make use of the structure of 5 and 1 more or 1 less (MP7).
