# Coordinates (age 8+)

Plot specified points on a coordinate grid and draw sides to complete a given polygon

Subject: Mathematics · Area: Geometry · Ages 8 to 9
Page: https://lightmysky.com/learn/mathematics/coordinates-age-8-mt_i5_HnoFOYw

## Ready when they can

- Plot points (1,1), (1,4), (5,4), (5,1) and join to make a rectangle
- Given three vertices of a square, plot the fourth vertex
- Complete a triangle by plotting the third vertex at given coordinates and drawing sides

## Lesson: Drawing shapes with coordinates

You already know how to plot a point on a grid using its coordinates, like (3, 2). Now you will plot several points and join them together to draw a shape. Plot each point first, then connect them with straight lines in the order you plot them.

**Example.** To draw a rectangle, plot (1,1), (1,4), (5,4), and (5,1). Connect each point to the next with a straight line, then draw one more line from the last point back to the first. Those four points make a rectangle.

*(drawing: A triangle has three corners and three straight sides connecting them.)*

**Tip.** If you're given three corners of a square or rectangle, look for the missing corner's numbers among the corners you already have. It shares its x-number with one neighbor and its y-number with the other.

**Example.** A triangle has corners at (2,1) and (2,6). The third corner is given at (7,3). Plot all three points, then draw three straight sides connecting them to complete the triangle.

**Recap.** Plot every point first, then connect them in order with straight lines, closing the shape back at the start.
