Coordinate Graphing Mystery Pictures

Plot the points, connect the dots in order, and a picture appears. Twelve mystery pictures on a first-quadrant or four-quadrant grid — each with an answer key.

Why mystery pictures work

Plotting forty points on a grid sounds like a chore — until a rocket or a cat starts to appear. The picture gives instant feedback, too: if one point is plotted in the wrong place, the drawing looks wrong, and students go back and check it themselves.

How to plot a point

  1. Start at the origin, where the axes cross.
  2. Move across by the first number (x). Right for positive, left for negative.
  3. Move up by the second number (y). Up for positive, down for negative.
  4. Mark the point, then draw a straight line from the previous point. When a new line starts, lift your pencil.

First quadrant or four quadrants?

Fifth graders usually work in the first quadrant, where every coordinate is zero or more. In sixth grade, students extend the grid into all four quadrants — choose “Four quadrants” to practice negative coordinates with the same pictures.

For quick practice reading points, try the coordinate plane worksheets, or print graph paper for students to design their own mystery pictures.

Frequently asked questions

What is a coordinate graphing mystery picture?

A list of ordered pairs that students plot on a grid and connect in order. When they are done, the lines form a picture — a house, a star, a rocket and more.

Can I use negative coordinates?

Yes. Choose “Four quadrants” and the picture is moved to the center of a −6 to 6 grid, so students practice plotting points with negative numbers.

Is there an answer key?

Yes. The answer key shows the finished picture drawn on the grid, with its name.

How many pictures are there?

Twelve: a house, star, heart, arrow, sailboat, fish, rocket, pine tree, crown, ice cream cone, cat and umbrella. Choose “All pictures” to print one of each.
