(7.6) Geometry and spatial reasoning. The student compares and classifies shapes and solids using geometric vocabulary and properties.
The student is expected to: (B) use properties to classify triangles and quadrilaterals.
7.6B INSTRUCTIONAL LESSON & ASSESSMENT
For this TEKS students should be able to compare and classify shapes using geometric vocabulary and
properties. Focus for this lesson is the use of properties to classify quadrilaterals. A review of properties and
and classification of triangles is included in Instructional/Student Activity #2.
BEFORE THE LESSON:
1. Make teacher transparencies.
2. Make one copy per student of page 3 – Quadrilaterals.
3. Make copies of Student Activity sheets, Open-Ended and Mini-Assessment.
4. Materials for Instructional/Student Activity #2: 1 set of Geometry Go Fishing Cards per
group of 4 students (copy on cardstock, laminate, and cut apart), Student Activity #2, 1
Geometry Go-Fishing Properties Chart per group of 4 students (copy the Quadrilaterals
chart on one side of cardstock and the Triangles chart of the other side of the cardstock,
then laminate), 1 Number cube per group of 4 students
MATH BACKGROUND
Understanding how to classify quadrilaterals
A polygon is a closed plane figure formed from line segments that meet only at their endpoints. A
quadrilateral is a 4-sided polygon. The sum of the measures of the four angles of any quadrilateral is
360  . Students in Grade 7 should be familiar with the attributes and classification of the following
quadrilaterals.

QUADRILATERALS
 A quadrilateral is a polygon. A polygon is a
closed plane figure formed by line
segments that meet only at their endpoints.
 A quadrilateral has four sides which are line
segments.
 Some quadrilaterals have special traits, so
they have special names: trapezoid,
parallelogram, rectangle, rhombus, and
square.
 The sum of the measures of the four angles
of any quadrilateral is 360.

7.6B STUDENT ACTIVITY #2
Geometry Go-Fishing
MATERIALS:
1 set of Geometry Go Fishing Cards per group of 4 students
Student Activity #2
1 Geometry Go-Fishing Properties Chart per group of 4
1 Number cube per group of 4 students
GOAL:
To make books of Geometry cards. Each book must have 4 cards: a figure card, a name card
that matches the figure, and two property cards that match the figure. The winner of the
game will be the player with the most books at the end of the game.
BEGIN:
Place the Geometry-Go-Fishing Property Chart in the center of the table.
Shuffle the cards and deal 6 cards to each player. Place the remaining cards face down in
the middle of the table (the TESKING TOWARD TAKS side up) for the DRAW PILE.
Each player rolls the number cube. The player with the largest number is Player 1. If there
is a tie for the largest number, roll again. Player 2 is to the left of Player 1. Player 3 is to
the left of Player 2, and Player 4 is to the left of Player 3.
RULES:
Player 1 looks at his/her hand of cards and secretly identifies a card needed to complete a
book. Player 1 asks any player for the card, saying, “Do you have the ______ card?” If the
player has that card, the player says, “Yes, I do” and gives the card to Player 1. Player 1
continues asking for cards and collecting cards until another player answers, “No, I don’t,
Geometry Go-Fishing.” Player 1 then draws a card from the top of the DRAW PILE.
Player 2 now begins his/her turn and follows the same rules as Player 1. The game continues
to the next player at the end of each player’s turn.
If any player makes a book of 4 cards at any time, he says “Geometry Book” and lays the 4
cards out for the rest of the players to see. If all players agree the book is correct, the
player places the four cards in a stack on the table in front of him. If the players agree the
books is not correct, the player returns the cards to his hand. Players may use the Geometry
Go-Fishing Properties Chart at any time during the game or to confirm a “Geometry Book” is
correct.
When the DRAW PILE is empty, play continues, but without the draw from the pile rule.
The game ends when any player has 6 Geometry Books.
