Grade 5 coordinates practice quiz: Identify plotted points.

📚 Topic Summary

The coordinate plane is like a map made of two number lines! The horizontal line is called the x-axis, and the vertical line is called the y-axis. Each point on the plane is identified by an ordered pair (x, y), where 'x' tells you how far to move along the x-axis, and 'y' tells you how far to move along the y-axis. To identify a plotted point, start at the origin (0, 0), move along the x-axis to find the x-coordinate, then move along the y-axis to find the y-coordinate.

This quiz will help you practice identifying points on a coordinate plane. Remember to always write the x-coordinate first and the y-coordinate second!

1. Definition: The point (0, 0) where the x-axis and y-axis intersect.
2. Definition: A plane formed by the intersection of a horizontal number line (x-axis) and a vertical number line (y-axis).
3. Definition: The horizontal number line on a coordinate plane.
4. Definition: The vertical number line on a coordinate plane.
5. Definition: A pair of numbers (x, y) that describes the location of a point on a coordinate plane.

✍️ Part B: Fill in the Blanks

Complete the following paragraph with the correct words. Words: x-coordinate, y-coordinate, ordered pair, origin, axes

The coordinate plane is formed by two perpendicular number lines called _____. Each point is located using an _____ consisting of two numbers. The first number is the _____, and the second number is the _____. The point where the two axes meet is called the _____.
