Find lengths using concrete models for standard units.
For Grade 2, this standard focuses on Find length (models) and prepares learners for increasingly complex tasks.
Standard 2.9A in Mathematics helps students understand Find length (models) and apply knowledge with confidence.
Use short exit tickets and tasks where students explain decisions, show multiple representations, or justify answers—directly aligned to 2.9A.
It lays groundwork for the next grade by deepening accuracy and flexibility with Find length (models), so students can tackle more complex problems later.
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to 2.9A.
Standard 2.9A describes the essential skills and understandings for Find length (models) in Grade 2. It clarifies the learning outcomes and what successful work looks like.
