Coordinate Graphing
Learning Objectives
- Plot points in the first quadrant
- Understand ordered pairs (x, y)
- Navigate using coordinates
- Identify patterns in coordinate graphs
Key Concepts
Coordinate Plane
A grid formed by two perpendicular number lines (axes)
Ordered Pair
(x, y) - the x-coordinate comes first, then y
Origin
The point (0, 0) where the axes meet
X-axis
The horizontal number line (left-right)
Y-axis
The vertical number line (up-down)
Theory
The coordinate plane is like a map that helps us describe exact locations using two numbers!
**"Crawl Then Climb" Rule:**
To plot (5, 3):
1. Start at the origin (0, 0)
2. **Crawl** right 5 units (x-direction)
3. **Climb** up 3 units (y-direction)
4. Mark your point!
**Reading Points:**
To find the coordinates of a point:
1. Drop straight down to the x-axis → x-coordinate
2. Go straight left to the y-axis → y-coordinate
3. Write as (x, y)
**Memory Tricks:**
- "x comes before y" (alphabetical order)
- "Run before you jump" (horizontal before vertical)
- Think of walking: move along the hallway (x), then take the elevator (y)
**Coordinate City:**
Imagine a city grid - to reach any location, you first go East/West (x), then North/South (y)!
Examples
Plot the point (4, 7)
Solution: Start at origin, move right 4, up 7
What point is 3 right and 5 up from origin?
Solution: (3, 5)
Points A(1,1), B(1,4), C(4,4), D(4,1) form what shape?
Solution: A square with side length 3
