Essential Questions: What is perimeter? How does knowing the attributes of plane figures help find the perimeter of an identified plane figure? What methods are used to measure perimeter/area? How does knowing the attributes of plane figures help find the area of a figure? How is area related to multiplication and addition? What is the difference between area and perimeter? How can the area of rectilinear figures be calculated?

Lesson seeds are ideas that can be used to build a lesson aligned to the CCSS. Lesson seeds are not meant to be all-inclusive, nor are they substitutes for instruction. When developing lessons from these seeds, teachers must consider the needs of all learners. It is also important to build checkpoints into the lessons where appropriate formative assessment will inform a teachers instructional pacing and delivery.
Unit/Cluster: Understand Concepts of Area and Relate Area to Multiplication and Addition/Geometric Measurement
Lesson Topic: Finding the area of a rectangle by tiling it and providing an opportunity for students to develop their own formula (rule) for finding the area of a rectangle.
Essential Questions
Enduring Understandings
Focus Standard(s)
It is critical that the Standards for Mathematical Practices are incorporated in ALL lesson activities throughout the unit as appropriate. It is not the expectation that all eight Mathematical Practices will be evident in every lesson. The Standards for Mathematical Practices make an excellent framework on which to plan your instruction. Look for the infusion of the Mathematical Practices throughout this unit.
Coherence of Standards Across-Grade Coherence: Content Knowledge from Earlier Grades
Within-Grade Coherence: Content from Other Standards in the Same Grade that Provide Reinforcement
RIGOR
Procedural Skill Students will accurately find the area of a rectangle using the formula.
Conceptual Understanding Students will use tiling to determine the area of a rectangle to generate the rule (formula) for finding the area of a rectangle.
Modeling/Application Students will apply their understanding of how the concrete models for the area of the rectangular-shaped carpet can be represented by the formula for area.
Student Outcomes
Method for Determining Student Readiness for the Lesson
Use the Warm Up (see “Learning Experience”) as a pre-assessment.
