Classify 2D figures based on presence or absence of parallel/perpendicular lines or specified angle sizes.
Teachers can use 4.6D to sequence instruction on Classify 2D figures and monitor progress toward mastery.
With 4.6D, Grade 4 students practice Classify 2D figures in multiple representations and contexts.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 4.6D.
Standard 4.6D describes the essential skills and understandings for Classify 2D figures in Grade 4. It clarifies the learning outcomes and what successful work looks like.
It lays groundwork for the next grade by deepening accuracy and flexibility with Classify 2D figures, so students can tackle more complex problems later.
Use short exit tickets and tasks where students explain decisions, show multiple representations, or justify answers—directly aligned to 4.6D.
