Multiply with fluency a three-digit number by a two-digit number using the standard algorithm.
The intent of 5.3B is to move students from guided examples to independent work with Multiply Fluently (3-digit × 2-digit).
Aligned tasks under 5.3B balance fluency and reasoning so students can explain decisions about Multiply Fluently (3-digit × 2-digit).
Students may rely on procedures without reasoning or mix key terms. Build in quick oral explanations, error analysis, and vocabulary supports tied to 5.3B.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 5.3B.
Standard 5.3B describes the essential skills and understandings for Multiply Fluently (3-digit × 2-digit) in Grade 5. It clarifies the learning outcomes and what successful work looks like.
It lays groundwork for the next grade by deepening accuracy and flexibility with Multiply Fluently (3-digit × 2-digit), so students can tackle more complex problems later.
