Compose and decompose a/b as a sum of unit fractions 1/b.
TEKS 3.3D provides a clear foundation for continued study of Compose/decompose fractions in future grades.
The intent of 3.3D is to move students from guided examples to independent work with Compose/decompose fractions.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 3.3D.
Standard 3.3D describes the essential skills and understandings for Compose/decompose fractions in Grade 3. It clarifies the learning outcomes and what successful work looks like.
Use short exit tickets and tasks where students explain decisions, show multiple representations, or justify answers—directly aligned to 3.3D.
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to 3.3D.
