Geometry in the Real World Assignment


I am sending home a paper copy of this assignment with your child today, but here is a digital copy (just in case they happen to lose the paper version!)

Geometry in the Real World Assignment
Due Friday, January 23rd.
Assignment Basics: Using Google’s My Maps Tool (, students will create a map with different polygons drawn on it (Part One).  Students will then record this information onto a table they create and answer questions about their map in complete sentences (Part Two).

--- Part ONE ---
Draw the following polygons accurately onto a map in My Maps. Then, in each “balloon” (the white box that pops up when you click your polygon), type in the definition for each.  Use the notes from class to help.  

(Regular) Parallelogram
Obtuse Triangle
(Regular) Pentagon
(Regular) Hexagon

How to Use My Maps
In My Maps, the draw a line/polygon tool is up the top and looks like this: SNP_3024944_en_v0.  Click it to draw a polygon on your map.  Be sure to connect your first point and last point to complete each polygon. To type the definition and change the name for each polygon, you’ll need to “Edit” its balloon.  To do this, click the polygon to see its balloon and then click the pencil in the lower right hand corner.  Please notice how the “Balloon” also shows you its perimeter and area.  This information will be used in part two of the assignment.

Important: You MUST be logged into your school Google Account first so you can save your map!  We log in to this account everyday, but if your child is still having difficulty, please send a note to school or email me at and I can help.  Mr. Piercey will also show students how to submit their maps during math class.

--- Part TWO ---

Once you have the polygons drawn on your map, complete parts A, B, C, D, E, and F below using a separate piece of Graph Paper:

  1. Choose AT LEAST FIVE of the polygons you’ve drawn on your map and put their information in a table similar to the example below (perimeter, area, sides, and vertices -- don’t forget the units!).

Polygon Name
Example: Triangle
4.32 miles
8.08 sq miles

  1. Pick THREE of your polygons (be sure to label which ones you use) and SUM UP their total area.  Don’t forget your units!  Show your work!
  2. Pick ONE of the polygons on your map and multiply its total perimeter by 10.  Label and show your work!  
  3. Which of your polygons has the greatest area?  Which has the smallest area?  What is the difference between these two areas?
  4. Explain why a square is also a rectangle AND a rhombus AND a quadrilateral.  
  5. Imagine that Bob is completing this assignment.  After completing the assignment, he decides to add the perimeter of his rhombus and pentagon together (His work is below).  Is Bob correct?  Explain why or why not (in complete sentences, please!).  
Challenge (optional): What is the actual total combined perimeter of Bob’s Rhombus and Pentagon (in feet)?

Parents: If your child needs additional time at school to work on this assignment outside of class hours, Mr. Piercey gets to school by 7:30 each morning.  He will gladly work with your child in the classroom during this time.  He will also be staying after school on Tuesday, January 20th until 4:15.  Please make sure to send a note to school if you’d like him to work with your child during either of these times.  You can also email Mr. Piercey at with any questions you have.  

Rubric: Your finished assignment (with part one and part two) will be scored on the following rubric

Part 1
All twelve polygons are clearly drawn and labeled on the map.  A clear definition for each polygon is within each “balloon”.  
All twelve polygons are on the map, but some definitions are lacking/missing.
Some polygons are missing or poorly drawn, definitions are either missing or incorrect.
Most polygons are missing or blank.  There are no definitions for the polygons.
This portion of the assignment is missing.
Part 2
All parts are complete and neatly and clearly labeled on graph paper.  All of the student’s work is clearly shown.
All parts of the assignment are complete with a few errors.  Parts of their work may be missing or incorrect.
Parts of the assignment are missing and/or their work contains multiple errors in calculation.  
Much of the assignment is incomplete or student work is difficult to read or understand.
This portion of the assignment is blank/never turned in.  
Overall score
E - Exceeds Expectations
M - Meets Expectations
W - Working Towards Expectations
C - Area of Concern
B - Blank
