Use right angles to identify acute, right, and obtuse triangles.
The intent of 4.6C is to move students from guided examples to independent work with Triangles by angles.
TEKS 4.6C provides a clear foundation for continued study of Triangles by angles in future grades.
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to 4.6C.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 4.6C.
Standard 4.6C describes the essential skills and understandings for Triangles by angles 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 Triangles by angles, so students can tackle more complex problems later.
