Meet the Coordinate Plane

Learn the axes, origin, and ordered pairs.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 79

A coordinate plane is a grid for finding exact spots. Two number lines cross at a right angle. The one going across is the x-axis. The one going up is the y-axis.
They cross at a point called the origin. It's the starting spot for every point.
An ordered pair gives directions. For 3 comma 5, start at the origin, go 3 across, then 5 up. Order matters!
The full plane continues past zero into four sections called quadrants. In Grade 5, we'll stay in this top right one, the first quadrant.
