converted meters to feet
create based scale (1cm = x ft)
Developed a bar scale on the map (100ft = x cm)
Asked how many cm is 2000 ft? Can we run this experiment? How can we modify it? Where can we run it?
I can also reverse that and have Dogs over Cats - that's the awesomeness that I can get away with - when it comes to ratios that I can't do with fractions.
