Explain how more/fewer parts affect the size of each part.
Teachers can use 2.3B to sequence instruction on Relative size of parts and monitor progress toward mastery.
TEKS 2.3B bridges prior learning and next steps in Mathematics, keeping Relative size of parts coherent across the year.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 2.3B.
Standard 2.3B describes the essential skills and understandings for Relative size of parts in Grade 2. It clarifies the learning outcomes and what successful work looks like.
It lays groundwork for the next grade by deepening accuracy and flexibility with Relative size of parts, 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 2.3B.
