Fifth Avenue in Manhattan, New York, divides the city into east and west. If you are on $41\mathrm{st}$ Street, you are on either East $41\mathrm{st}$ Street or West $41\mathrm{st}$ Street, depending on which side of Fifth Avenue you are.

Suggest two reasons why East and West streets are used instead of using negative numbers for addresses. 

The lowest place in the southern and western hemisphere is the Laguna del Carbon in Argentina, which is at an altitude of 105 meters below sea level.
Represent '105 meters below sea level' as an integer.

The lowest place in the southern and western hemisphere is the Laguna del Carbon in Argentina, which is at an altitude of $105$ meters below sea level.

How do altitudes reported 'above' or 'below' sea level relate to absolute value? Explain.

The lowest place in the southern and western hemisphere is the Laguna del Carbon in Argentina, which is at an altitude of $105$ meters below sea level.

Find as many words as you can that represent 'positive' and 'negative'. Fill in a table like this one, and share your results so that the class as a whole can create a thesaurus of words that represent 'negative' and 'positive'. Add more rows as necessary.

Roald Amundsen was an explorer from Norway who explored both the Arctic and the Antarctic, and was the first person to travel to the South Pole. In a race against explorer Robert Falcon Scott, Amundsen's expedition left Kristiansand, Norway, in August 1910 and arrived at the South Pole in December 1911 , about one month before Scott.

Along his voyage, Amundsen experienced a wide range of temperatures at locations like those in the table below.

Arrange the locations according to their temperature from lowest to highest.
