Compose 2D shapes and 3D solids with given properties or attributes.
In Mathematics, 2.8D defines what success looks like for Compose shapes/solids—from core skills to real‑world use.
For Grade 2, this standard focuses on Compose shapes/solids and prepares learners for increasingly complex tasks.
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to 2.8D.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 2.8D.
Standard 2.8D describes the essential skills and understandings for Compose shapes/solids in Grade 2. It clarifies the learning outcomes and what successful work looks like.
It lays groundwork for the next grade by deepening accuracy and flexibility with Compose shapes/solids, so students can tackle more complex problems later.
