Measurements of Polygons (Lesson Plan)

Week Of: January 12-16, 2009
MONDAY 1.12.2009- TUESDAY 1.13.2009

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

WARM UP: (BCR)
Draw and define a triangle and a pyramid. Recall our past lessons.

Goal(s)/ Expectation(s)
T1 GOAL: Identify 2D and 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 a triangle and a pyramid relate to each other?

PRODUCT: Venn Diagram comparing and contrasting a triangle and a pyramid.

Guided Instruction & Independent Practice/Study
WHOLE GROUP INSTRUCTION:
Show and discuss this PowerPoint Presentation

SMALL GROUP INSTRUCTION:
Break the class according to the students’ ability level. Write comparison and contrast between triangle and pyramid using a Venn Diagram.

T1: Draw a triangle and a pyramid.
T2: Draw a triangle and a pyramid and describe angles and sides.
T3: Relate the triangle and pyramid to things you see in the environment and community.

ASSESSMENT:
Online game: Complete the designs by arranging geometric shapes provided.

WEDNESDAY 11.7.2009 THURSDAY 1.8.2009 DC BAS

FRIDAY 1.9.2009
Standard(s) 6M3 Develop strategies to find the area and perimeter of complex shapes.

WARM UP: (BCR)
Draw three different triangles that can not be divided into symmetrical halves.

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

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

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

Guided Instruction & Independent Practice/Study

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

SMALL GROUP INSTRUCTION:
Break the class according to the students’ ability level. Answer page 10-11 Investigation 1: Measuring Perimeter and Area, Connected Math.

Measure only the area of the figures:
T1: Designs A, B, C.
T2: Designs A - F
T3: Designs A - J

ASSESSMENT:
Online game: Drag the 2D tiles to the shape’s outline. Try to fill the space as quickly as possible:
