- Definition
A grid is a pattern of lines, like on a map or a graph, that helps you find exact spots or see how things are spread out. Think of it like a checkerboard that helps you pinpoint locations.
To find the location (3, 4) on a coordinate grid, you start at zero, move 3 spaces to the right, and then move 4 spaces up.
How to teach this in 30 seconds
Try this analogy: A grid is like a checkerboard, with straight lines going up and across to create specific squares you can locate.
Ask your child: If we look at this map, what number and letter do we use to find the park?
Common mix-up: Kids often mix up the directions, thinking 'up 3, over 2' is the same as 'over 3, up 2.' The mathematical rule for a coordinate grid is to always count across first, then count up or down.
Examples
- Using the numbers and letters on the side of a city map to find a specific street intersection.
- Placing a point on graph paper where the grid lines cross to show data on a chart.
grid is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
