Multiplication and the Meaning of the Factors

Author: Great Minds, as featured on EngageNY

• Description
• Files

Mathematically:

• Uses repeated addition as an entrance point (not an ending point) for students learning the meaning of multiplication as equal groups (3.OA.A.1)
• Devotes significant time to understanding the concept of multiplication as opposed to the operation of multiplication
• Starts the year right away with major work of the grade, and begins the journey towards an important fluency expectation (3.OA.A.2)
• Connecting repeated addition number sentences to multiplication number sentences gives students opportunities to look for and make use of structure (MP.7)

In the classroom:

• Uses multiple concrete representations and visual models to make the mathematics explicit
• Prompts students to share their developing thinking and understanding (Student Debrief and throughout lessons)
• Provides opportunities and suggestions for differentiation
• Gives formal and informal opportunities for teachers to check for understanding

• Making the Shifts

How does this set of lessons exemplify the instructional Shifts required by CCSSM?

 Focus Belongs to the major work of third grade Coherence Builds upon second grade work with equal groups of objects (2.OA.C.4) and lays the foundation for much of the work in third grade Rigor Conceptual Understanding: primary in these lessons (3.OA.A.1) Procedural Skill and Fluency: secondary in these lessons Application: secondary in these lessons (3.OA.A.3)
