Below is a map of a community. What is the distance between the school and the pond?

In this lesson you will learn to graph and solve real-world

problems by using a coordinate plane.

Let’s Review F (-8,-4)

G (3,-4)

F G

|-8-3|= |-11| = 11 OR

|3 – (-8)| = |11| = 11

A Common Mistake

Begin by moving along the y-axis first, and then along the x-axis when finding an ordered pair.

(6,4)

A Common Mistake

Returning to the origin after plotting the x value, and then moving on the y-axis.

Extension Activities

Room Map:

1. Create a map of your classroom on a piece of graph paper.

2. Draw landmark and objects at various locations in the room.

3. Challenge a friend to find the distance between different points and objects.

Extension Activities

Community Map:

Use a piece of graph paper and draw a map of your community.

Create a key to show each landmark.

As an extra challenge, draw your map to scale, and record the distances between different landmarks.

Share your map with the class.
