6.8(A) Extend previous knowledge of triangles and
their properties to include the sum of angles of a
triangle, the relationship between the lengths of sides
and measures of angles in a triangle, and determining
when three lengths form a triangle
6.8D- Determine solutions for problems involving the
area of shapes and prisms where dimensions are
positive rational numbers.

Objective/Key Understanding:
6.8(A) SWBAT extend previous knowledge of triangles and their properties to
include the sum of angles of a triangle, the relationship between the lengths of
sides and measures of angles in a triangle, and determining when three
lengths form a triangle extend previous knowledge of triangles and their
properties to the relationship between the lengths of sides and measures of
angles in a triangle.
6.8D-SWBAT determine solutions for problems involving
the area of shapes where dimensions are positive rational
numbers.
6.8B- SWBAT model area formals for parallelograms
trapezoids, and triangles by decomposing and rearranging
part of these shapes.

Engage: DAY 1 POP QUIZ! Give student Module 15 Mixed Review Test Prep pg 442. SW independently complete the
Are you Ready pg. 444. Show Real-world video to preview the lesson. SW work in pair to complete the Reading
Start up pg. 445 and read pg. 446. Pull small groups who did not master the quiz. All other SW will play vocabulary
Taboo game in partners when finished. Student will draw a card with vocabulary words previously learned plus all
polygons and types of triangles. SW describe the word without saying the word while partner tries to guess. TW
create mini quiz with vocabulary and 6.8A to assess knowledge of polygons at the end of class.
Engage: Area VS Perimeter. SW work in groups to create a T-Chart that lists definitions, key words, and pictures to
represent Area and perimeter. How do you find the area of a rectangle?
Brainpop video area of polygons-https://www.brainpop.com/math/geometryandmeasurement/areaofpolygons/
Do you know how to change a rectangle into two identical right triangles?
Explore: 16.1 Explore Activity Area of a parallelogram and Trapezoid. Explore 16.2 Area of triangle
Explain: TW explain how important it is to looks at the reference chart to locate the formulas; students must write
formula first and then plug in dimensions underneath. SW discover the need to use the proper order of operations
when solving. SW tri-fold a foldable with rectangle, parallelogram, trapezoid. Include: definitions, pictures, and
formulas. Be sure students are using the STAAR Reference chart. Interactive whiteboard for examples
Reteach how to multiply with decimals and fractions when needed.
Elaborate: Guided practice ( May omit Rhombus!) 16.1—16.2 and Independent practice.

Module 16
Critical Writing Prompt:
How can you find the areas of a
parallelogram and trapezoid?
How can you tell that a quadrilateral is a trapezoid rather than a parallelogram?
How do you find the area of a trapezoid? How do you find the area of a triangle?
Small Group Purposeful Talk Question Stems:
How are the area of a trapezoid and the
area of a parallelogram?
What is the relationship between the
rectangle, trapezoid, and the
parallelogram?
What does it mean in a formula when the variables are next to each other without and
operation?
Module 15 Mixed Review Test Prep pg 442
What is the relationship between the area of a triangle and a rectangle/parallelogram?
Module 16.1 and 16.2 Quizzes online
Why is area expressed in square units?
Vocabulary:
Polygons: triangles, trapezoid, parallelogram. Area, perimeter, formulas, variables
Rigor & Relevance: (Real World Connection)
Module 16 Real –World Video: Quilting,
painting, and other art forms use familiar
geometric shapes, such as triangles and
rectangles to buy enough supplies for a
project, you need to find or estimate the
areas of each shape in the project.
Can you Identify the geometric shapes in the
problems, then use their dimensions to find
the area and volume of the shapes?
