How to do a coordinate mystery picture
Start with Line 1. Plot its first point, then the next, and join them with a ruler. Keep going in order to the end of the line, ticking each point off the list as you plot it. Then lift your pencil and do Line 2 the same way. Points in the Dots box get a small dot each. When every line is drawn, write what your picture is at the bottom and color it in.
To plot a point, count across first and then up: (4, 7) is 4 across and 7 up. On four quadrant grids, negative numbers go left or down. For plain ordered pair practice first, see the coordinate plane grids and the plot-the-points sheets in geometry worksheets.
Printing tip: print at 100 percent (actual size) on US Letter paper. The sheets are black and white.
Questions
What is a coordinate graphing mystery picture?
A grid and a list of ordered pairs. Plot each point, join the points of each line in order with a ruler, and a picture appears. Children practise reading and plotting coordinates without a page of bare drills, and they can check their own work: if the picture looks wrong, a point is in the wrong place.
Are these free?
Yes. All 16 pictures and their answer keys are free to print for home and classroom use, with no signup.
Which level should I use?
Easy (0 to 10) suits fourth and fifth graders meeting ordered pairs for the first time. Medium (0 to 20) has more points on a finer grid. Four quadrants (-10 to 10) adds negative numbers, which most children meet in sixth grade.
How do I plot a point like (3, 7)?
Start at 0. The first number tells you how far to go across, the second how far to go up. So (3, 7) is 3 across and 7 up. In four quadrants, a negative first number means go left, and a negative second number means go down: (-6, -3) is 6 left and 3 down.
What do Line 1, Line 2 and the dots mean?
Each line is drawn on its own. Join its points in order, then lift your pencil and start the next line at its first point. A point in the Dots box is not joined to anything: draw a small dot there (eyes, buttons, ornaments).
