Represent one‑ and two‑step problems involving addition/subtraction to 1,000 using models, number lines, and equations.
Aligned tasks under 3.5A balance fluency and reasoning so students can explain decisions about Add/subtract models & equations.
The intent of 3.5A is to move students from guided examples to independent work with Add/subtract models & equations.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 3.5A.
Standard 3.5A describes the essential skills and understandings for Add/subtract models & equations 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 Add/subtract models & equations, 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 3.5A.
