Classify and sort solids (sphere, cone, cylinder, rectangular prism, triangular prism) by attributes.
TEKS 2.8B bridges prior learning and next steps in Mathematics, keeping Sort 3D solids coherent across the year.
For Grade 2, this standard focuses on Sort 3D solids and prepares learners for increasingly complex tasks.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 2.8B.
Standard 2.8B describes the essential skills and understandings for Sort 3D solids in Grade 2. It clarifies the learning outcomes and what successful work looks like.
Use short exit tickets and tasks where students explain decisions, show multiple representations, or justify answers—directly aligned to 2.8B.
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to 2.8B.
