Represent and solve addition/subtraction word problems with any term unknown.
With 2.7C, Grade 2 students practice Unknowns in problems in multiple representations and contexts.
The intent of 2.7C is to move students from guided examples to independent work with Unknowns in problems.
Use short exit tickets and tasks where students explain decisions, show multiple representations, or justify answers—directly aligned to 2.7C.
It lays groundwork for the next grade by deepening accuracy and flexibility with Unknowns in problems, 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 2.7C.
Standard 2.7C describes the essential skills and understandings for Unknowns in problems in Grade 2. It clarifies the learning outcomes and what successful work looks like.
