MAP SCALE

LESSON 4

VIDEO STARTER:  SCALE - YOU NEED THIS FOR THE ACTIVITY

NOTEBOOK STARTER (WRITE IN NOTEBOOK:  QUESTION AND ANSWER):  WHY WOULD THESE LOCAL COMPANIES RELY ON SCALING WHEN ENGINEERING OUR REGION?

FOR YOUR NOTEBOOK:

Lesson 4:  Map Scale 1

Types of Scaling:

  1. Statement -

    1. The scale is written out. 

    2. Example:  1 cm on the map is equal to 1 meter in the world.

  2. Line Scale -

    1. A Bar on the map has notches or marks on it like a ruler.  Each notch represents a different amount in real life. 

    2. Example: (copy from front board)

  3. Representative Fraction -

    1. It's written as a ratio. 

    2. Example:  1:10 - This means that for every measurement of 1 on the map, the real world is 10X that amount!  So the map is realistically 1/10 the size of what it represents.

CREATE A MAP OF YOUR CLASSROOM

DIRECTIONS

DIRECTIONS

On a grid paper, you are to draw a map of your classroom.  IT NEEDS TO BE PRECISE!  TO SCALE!  Here is how we’re going to do it...

Part 1:  ROUGH DRAWING

  1. Draw a rough sketch of the classroom as if you were a drone looking down.   This view is a topographical one.  Include all student tables, poles, teacher desks.

  2. Measure a section of the room with a meter stick (From Lab Terms Poster to BFG Tshirt).  We will be measuring in meters!  If it's 20 meters long, write that down!  LABEL IT!


Part 2:  DETERMINE A SCALE  

Notice that your notebook is smaller than your room... :-) I get it...  You knew that.  But you now need to figure out what every block on your notebook should represent in real life.  That is for us to decide.  

Room length ______ m

Paper grid _______ blocks

Scale _____:_____


Create a space in the upper right corner of your grid paper for your map LEGEND.


Part 3:  FINAL PRODUCT 

You need to create a scaled map of our classroom.   INCLUDE THE FOLLOWING:

  1. All student tables, poles, teacher desks.

  2. Legend with all 3 types of map scaling techniques. 

    1. Statement

    2. Line Scale

    3. Representative Fraction
