Examine and model parts of a system and their interdependence.
In Science, 4.5D defines what success looks like for Systems & system models—from core skills to real‑world use.
For Grade 4, this standard focuses on Systems & system models 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 4.5D.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 4.5D.
Standard 4.5D describes the essential skills and understandings for Systems & system models 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 Systems & system models, so students can tackle more complex problems later.
