 Locations, Positions, Plans, and Routes! 

How do we know where things are and how do we talk about the place or position something is in? From the previous blog post, we know that the cardinal points are one way we can understand the location or position of something. To review the cardinal points, or cardinal directions are north, south, east, and west. Aside from the cardinal points, we can understand the location of something by saying whether it is above, below, to the left of, or to the right of something else. By doing this we are understanding the position of one thing in relation to something else. 

Take a look at the picture of a park below and use the new vocabulary you have learned to describe the position and location of things in the picture! The swings are ________ the treehouse. The clouds are _______ the grass. The stairs are _______ the slide. The trees are _______ the blue sky. Find the answers at the bottom of this blog post. 

Plans, also known as maps, show us where things are! When you are in a new place it is helpful to get a map of the city to help you figure out where the things you want to see are. 

In this map of San Francisco can you find the golden gate bridge, the financial district, the mission district, and the SF zoo? 

Answers: The swings are to the right of the treehouse. The clouds are above the grass. The stairs are to the left of the slide. The trees are below the blue sky.

Our World

Our World 

The world is a big and beautiful place. We can understand our world by looking at different visual representations of our world, such as maps and globes. Maps are in two dimensions, while globes are in three dimensions! Because globes are in three dimensions they help us get a better sense of what our world really looks like from space.  

Important vocabulary:

Explore this INTERACTIVE WORLD MAP  to get a better sense of our world and all its places!

How is our world represented and understood?

 Our world is a sphere. The sphere of our world is divided into two parts. The two parts of the world are the southern hemisphere and the northern hemisphere. The two hemispheres are divided by an invisible line called the equator. At each furthermost point of each hemisphere, there is a pole. The poles are on either side of another invisible line called the earth's axis. In the southern hemisphere there is the south pole and in the northern hemisphere the north pole. 

Important vocabulary:

Sphere 

Southern Hemisphere 

Northern Hemisphere 

Equator 

Axis

South Pole 

North Pole 

The Cardinal Points

The world is also understood in terms of cardinal points or cardinal directions. The four cardinal directions are north, south, east, and west! Listen to this song to learn the cardinal points!
