Origin and axes identification worksheet Grade 5

📚 Topic Summary

The coordinate plane is a flat surface formed by two number lines that intersect at a right angle. The horizontal number line is called the x-axis, and the vertical number line is called the y-axis. The point where the two axes meet is called the origin. Understanding these basics helps us locate points on the plane.

Think of the x-axis as your street, showing how far left or right you go from the center. The y-axis is like the avenue, showing how far up or down you go. The origin is right where the street and avenue cross!

🧠 Part A: Vocabulary

Match the following terms with their definitions:

1. Term: X-axis
2. Term: Y-axis
3. Term: Origin
4. Term: Coordinate Plane
5. Term: Coordinates

1. Definition: The horizontal number line in a coordinate plane.
2. Definition: The point (0, 0) where the x-axis and y-axis intersect.
3. Definition: A plane formed by the intersection of a horizontal number line (x-axis) and a vertical number line (y-axis).
4. Definition: The vertical number line in a coordinate plane.
5. Definition: A set of values that show an exact position on a coordinate plane.

Write the correct number of the definition next to the term:

• X-axis: ____
• Y-axis: ____
• Origin: ____
• Coordinate Plane: ____
• Coordinates: ____

✍️ Part B: Fill in the Blanks

Complete the paragraph using the words provided: horizontal, vertical, origin, axes, coordinate plane.

The _______ is a flat surface formed by two number lines, called _______. The _______ axis runs left to right, and it is also known as the _______ axis. The _______ axis goes up and down. The point where the two lines intersect is called the _______, and it is at position (0, 0).

🤔 Part C: Critical Thinking

Imagine you are giving directions to someone using a coordinate plane. How would you explain the importance of the origin and axes to help them find a specific location?
