- Definition
Imagine a graph with two lines crossing in the middle; a quadrant is one of the four sections created by those crossing lines.
When plotting a point like (3, 5) on a grid where all numbers are positive, you are working in the first quadrant.
How to teach this in 30 seconds
Try this analogy: A quadrant is like one of the four squares you get when you fold a piece of paper in half twice.
Ask your child: If you draw a big plus sign on paper, how many boxes does it make?
Common mix-up: Kids often think the quadrants are numbered clockwise like a clock. The quadrants are numbered in a counter-clockwise C-shape, starting from the top right.
Examples
- A full graph has four quadrants that divide the space into top-right, top-left, bottom-left, and bottom-right sections.
- The top-right section is the first quadrant, which is the one most commonly used in early math.
quadrant is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
