MONDAY

11.24.2008

6M6 Identify, measure, describe, classify, and construct various angles, triangles, and quadrilaterals; measure the interior angles of various polygons.

WARM UP: (BCR)
Write comparison and contrast between two shapes using a Venn Diagram.

T1 GOAL: Identify 3D shapes, and lines of symmetry.
T2 GOAL: Describe shapes according to congruence and similarities.
T3 GOAL: Relate the different geometrical shapes to what you see in your environment.

ESSENTIAL QUESTION:
How does geometry affect our real world?

PRODUCT:
Analysis of the PowerPoint Presentation of “Zoom In Geometry”

WHOLE GROUP INSTRUCTION:
What might images of buildings in Washington DC teach us about symmetry and geometry in our world?

6M3 Develop strategies to find the area and perimeter of complex shapes.

WARM UP: (BCR)

Draw two different triangles that can be divided into symmetrical halves.

T1 GOAL: Use two basic shapes to make another basic shape (two triangles to make a square)
T2 GOAL: Measure the perimeter of basic shapes using a ruler.
T3 GOAL: Subdivide complex shapes into basic shapes and calculate perimeter using manipulative.

ESSENTIAL QUESTION:
How do we find the perimeter of basic and complex shapes?

PRODUCT:Completed activity sheet on finding the perimeter of a shape.

WHOLE GROUP INSTRUCTION:
Discuss to the class how to find the perimeter of a polygon:
