Examine and model parts of a system and their interdependence.
Teachers can use 3.5D to sequence instruction on Systems & system models and monitor progress toward mastery.
Standard 3.5D in Science helps students understand Systems & system models and apply knowledge with confidence.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 3.5D.
Standard 3.5D describes the essential skills and understandings for Systems & system models in Grade 3. 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.
Use short exit tickets and tasks where students explain decisions, show multiple representations, or justify answers—directly aligned to 3.5D.
