1.3.2 Practice · The Global Grid

Let’s fill out your paper

Tiny steps. One thing at a time. Get a pencil.

Step 1 of 8

Step 1

Get the paper

Do this now In Apex, open Practice: The Global Grid. Tap the little print / paper icon. Print it (or take a photo of it). Put it next to you.

Your paper has a round world map and two charts. It looks like the picture at the bottom of this page.

Do not google the answers. Only the last tiny question uses a website.

Step 2

The two numbers (super easy)

Every place on Earth has two numbers. Like a secret address.

Latitude = up or down

N means toward the cold top (North Pole).

S means toward the cold bottom (South Pole).

The middle belt is the equator. That is 0.

Longitude = left or right

E means east (right on most maps).

W means west (left on most maps).

The middle zipper is the prime meridian. That is 0.

Remember like this First number = how far up or down.
Second number = how far left or right.
Example: 30° S, 90° E means “a little down, then a lot to the right.”

Step 3

How to put a dot on the round map

Your paper’s map is a circle. The North Pole is in the middle. The farther out you go, the more south you are.

  1. 1 Read the first number. N = closer to the middle. S = closer to the outside edge.
  2. 2 Read the second number. E is toward Asia (right side). W is toward America (left side).
  3. 3 Put your pencil where those two ideas meet.
  4. 4 Make a fat dot. Write a tiny 1, 2, 3, or 4 next to it.
If you get lost Find land you know first (Africa near the bottom, America on the left, Australia near the bottom-right). Then scoot your pencil to the numbers.

Step 4 · question 1a · 2 points

Put 4 dots on the map

Do this on your paper On the round map, put 4 dots. Number them 1–4.

Tap “Show me” after you try, to peek at our map.

Step 5 · question 1b · 2 points

Name the land or water

Do this on your paper In the chart under the map, write a continent (land) or an ocean (water) for each row.

Step 6 · question 1c · 8 points

Tell how you found one dot

This one is worth a lot. Write a few sentences. You can copy these words and change the numbers if you pick a different dot.

Do this on your paper Under 1c, write the paragraph. Draw a tiny + if you want (a across line and an up-down line, with an X where they cross).

Write something like this

I used 30° S, 90° E. First I looked at 30° S. S means south, so I went toward the outside of the circle, not the middle. Then I looked at 90° E. E means east, so I went toward the Asia / Australia side of the map. I put a dot where those two meet. That spot is in the Indian Ocean.

Step 7 · questions 2a and 2b · 12 points

Now find four cities

Do this on your paper Find each city on the same round map. Write close-enough numbers. Then pick ONE city and write how you found it.
Still no google Write what your map shows. Close is okay. They said “approximate.”

2b — you can copy this for Tokyo

I found Tokyo by looking for Japan, on the right side of the map near Asia. It is north of the equator, so I used N. It looks about 35° N. It is east, so I used E. It looks about 140° E.

Step 8 · question 2c · then done

One exact lookup — then turn it in

This is the only time you may use the internet.

  1. 1 Open latlong.net
  2. 2 Type one city, like Tokyo, Japan.
  3. 3 Copy the two numbers it gives onto 2c.
