Model the action of joining to represent addition and separating to represent subtraction.
Standard K.3A in Mathematics helps students understand Model addition/subtraction (join/separate) and apply knowledge with confidence.
The intent of K.3A is to move students from guided examples to independent work with Model addition/subtraction (join/separate).
Standard K.3A describes the essential skills and understandings for Model addition/subtraction (join/separate) in Grade K. It clarifies the learning outcomes and what successful work looks like.
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to K.3A.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to K.3A.
It lays groundwork for the next grade by deepening accuracy and flexibility with Model addition/subtraction (join/separate), so students can tackle more complex problems later.
