Quadrilateral Unit
A Five Day Quadrilateral Unit Includes
Activities, Guided Power Point, Task Cards, In
depth thinking, and an assessment
2
5 Day Geometry Unit

• Includes the following
• Slides 3-23 Day One Slides 3-18 includes a
  guided geometry lesson in which different types
  of quadrilaterals and their properties are
  introduced. Slides 19-23 contain a Quadrilateral
  booklet for students to keep. As you are
  discussing the quadrilaterals and their
  properties, students can record them and practice
  drawing them in their own quadrilateral booklet.
  To use, cut down the dotted line in the middle of
  the page and staple together to make a book.
• Slides 24-31 Day Two Property sort. Students
  will break into partners or small groups. They
  will take the 8 polygons on slides 26 and 27.
  They will then cut out the pictures and
  attributes of the polygons on pages 28 and 29 and
  place them under the correct polygon on pages 26
  and 27. They will also have a reflection piece
  where they will write about their findings.
• Slides 32-46 Day Three Task Cards. Students
  will break into small groups or partners and
  complete the geometry task cards on the
  quadrilaterals and polygons. A recording sheet
  and answer card has been included.
• Slides 47-51 Day Four Comparing and
  contrasting quadrilaterals. Students will cut
  out quadrilaterals and choose 2 to compare and
  contrast. They will then take a venn diagram
  card and compare the 2 using the venn diagram.
  They will complete at least 5 diagram cards and
  the writing/reflecting activity at the end of day
  4.
• Slides 52 and 53 Geometry Assessment Students
  will review the terms and quadrilaterals and then
  take an assessment on what they have learned.

Quadrilaterals
Day 1 Guided lesson. Use the power point
presentation on slides 3-17 to introduce
quadrilaterals. While you are introducing the
quadrilaterals, have students take notes and
complete their quadrilateral book on slides
18-22.

Quadrilaterals
E.Q. What are the properties of quadrilaterals?
5
Drag the examples of quadrilaterals to the
example side and the Non-Examples to the
Non-Example Side.

With your group or partner, discuss what you
notice about these examples
8
They all have Four Sides They all have Four
Corners (Angles) Some have 4 equal sides Some
have 2 sets of equal sides What else can you add
to the list?
9
Shapes that have four sides can be grouped into
one big category
Quadrilaterals
10
Record in your Quadrilateral Book
Trapezoid
Properties Only ONE set of parallel sides.
When proving if a figure is a trapezoid, it is
necessary to prove that it has 2 sides that are
parallel and 2 sides that are not.
11
Record in your Quadrilateral Book
Parallelogram
Properties Has Two sets of parallel sides. Two
sets of sides that are the same length. Opposite
angles are the same.
12
Record in your Quadrilateral Book
Rectangle
Properties 4 Right Angles, 2 sets of parallel
sides, 2 sets of sides are the same length
13
Record in your Quadrilateral Book
Rhombus
Properties 4 equal sides, 2 sets of parallel
sides
14
Record in your Quadrilateral Book
Squares
Properties All sides are equal, 2 sets of
parallel sides, All angles are right angles.
15
Based on our observations and properties of our
quadrilaterals, discuss with your partner or
group Is it possible for a square to be a
rectangle? Why do some quadrilaterals look so
much alike? Is a rectangle a rhombus? Can some
shapes be called other names?
16
Place the shapes into the correct column
Parallelograms or Trapezoids
Parallelograms- Two pairs of parallel sides Trapezoids- One pair of parallel sides

Trapezoid
Square
Rhombus
Parallelogram
Rectangle

Quadrilaterals?
Yes No

18
Journal or Summary Explain the properties of
quadrilaterals. Choose 2 quadrilaterals. Draw
and label each. Then, discuss how these two
quadrilaterals are alike and different.
