problem_activity: Narrative
The purpose of this Number Talk is to elicit strategies and understandings students have for adding and subtracting 0 and 1. These understandings help students develop fluency with the count sequence and adding and subtracting within 5.
When students use their knowledge of the count sequence when they add or subtract 1, they look for and make use of structure (MP7).
