Lesson 11 - Drawing shapes in the coordinate plane.
Objective - You can draw a polygon in the coordinate plane using the attributes of
polygons and ordered pairs.
Vocabulary
coordinate plane
parallelogram
quadrilateral
right angle
trapezoid
right triangle
square
vertex/vertices
rectangle
1.) Activate students' background knowledge about coordinate planes/graphing and the
attributes of quadrilaterals.
2.) Show Learnzillion video 1706 and Guided Practice.
3.) Students complete the Guess My Shape activity.



Give each student 1 copy of each the Guess my Shape page FIRST - Have them draw and
then identify the coordinates of the vertices of their four shapes. When they have
finished this task, give them a blank Partner Page. The student fills out the Figure _ and
coordinates ONLY of the partner page.
The partner then takes the partner page and tries to plot the shape from the coordinates
the first person wrote. Every student should write their coordinates on B
If you have an odd number of students just have students pass their partner page one to
the left so everyone has a partner page to fill out and one to plot.
4.) Exit Ticket
5.) Extra time - Students may play Battleship game.
Guess My Shape!
Plot the following shapes on your coordinate plane.
You may make them any size and orientation that you wish, but be sure that they all fit
onto your coordinate plane without touching each other or extending off of the graph.
Label each shape with a letter of the alphabet (you do not have to go in order) for
example, you could have Figure A, Figure Q, Figure M, and Figure P.
Square
Trapezoid
Rectangle
Parallelogram
Write the coordinate pairs for each
vertex of your shape.

When you have double checked that your shapes and coordinate pairs are correct, write
the shape Figure labels and their coordinate pairs on your partner's paper. Be sure to mix
them up so it isn't easy for your partner to guess your shapes!
When you and your partner are both finished, give each other the "partner paper" and see
if you can plot and name your partner's shapes from his or her coordinate pairs.
Guess My Shape! Partner Page
Plot the coordinate pairs your partner provided and try to identify which shape each
Figure represents.

Exit Ticket - You can draw a polygon in the coordinate plane using the attributes of
polygons and ordered pairs.
1.) A square has vertices at point (2, 3) and
point (6, 7).
What is the side length for the square? (Plot
the shape to show your thinking.)
2.) I am plotting an isosceles trapezoid on the coordinate plane. The bottom has vertices at (2,
10) and (8,10).
The top, left vertex is 3 steps away from the bottom left vertex (2 steps "North" on the yaxis, 1 step "East" on the x-axis).
What are the two top coordinates of my isosceles trapezoid? (Plot the shape to show your
thinking.)
