Represent a number between benchmark multiples (10, 100, 1,000, 10,000) on a number line and use to describe relative size and round whole numbers.
The intent of 3.2C is to move students from guided examples to independent work with Number line & rounding.
Teachers can use 3.2C to sequence instruction on Number line & rounding and monitor progress toward mastery.
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to 3.2C.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 3.2C.
Standard 3.2C describes the essential skills and understandings for Number line & rounding 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 Number line & rounding, so students can tackle more complex problems later.
