OBJECTIVE:           How do we find actual
distances using a scale map?


                                  Do Now

 1.) Convert $8,000 US dollars to Euros.
 (1 US Dollar = 0.7846 Euros)



3.) Using a scale of 2 cm = 5 ft, find the
length of a model if a real truck is 38
feet long.




                                             1

Anticipatory Set
1.) How are maps drawn so that they look exactly like
the area that they represent?




2.) Why is it important to draw a map to look exactly
like the area it represents?
