Coordinate graphing pictures.
Plot the reveal.
Plot ordered pairs to reveal 12 original pictures. Start in the first quadrant, then use signed coordinates. Separate stroke lists tell you exactly when to lift your pencil.
12 different pictures.
Two coordinate ranges.
Separate named answer keys.
Read the stroke breaks before you draw
A short sample is (2,3) → (8,3) → (8,7) → (2,3). It makes one closed triangle. A second list begins a new stroke: lift your pencil before its first point. Do not create an extra joining line between the two lists.
| Worksheet IDs | Coordinate range | Distinct picture subjects |
|---|
| CG01–CG06 | 0 to 20 on x and y | House, sailboat, rocket, crown, tree, fish |
| CG07–CG12 | −10 to 10 on x and y | Umbrella, cat, butterfly, mountains, teapot, robot |
All listed coordinates are integers within the worksheet range. The arrow/order in a list tells you what to connect, while LIFT PENCIL separates independent details. The student preview does not reveal the finished line drawing; the answer page uses exactly the same coordinates.

Verify the grid before you trust the points
A coordinate picture depends on one shared assumption: every grid square represents the same step on both axes. If the horizontal and vertical spacing differ, a shape that should be square will look stretched, and diagonal segments will change angle. Before plotting, confirm the origin, the direction of positive x and positive y, and the step size printed on each axis.
Read each ordered pair as two separate decisions. The first number moves along the horizontal axis; the second moves along the vertical axis. Say both aloud before marking, for example 'three right, two up'. This slows the hand enough to catch swapped values, which are the most common cause of a picture that is recognisable but distorted.
- Locate the origin and confirm which direction is positive on each axis.
- Check that one grid square equals the same step horizontally and vertically.
- Read the first coordinate, move horizontally, then read the second and move vertically.
- Mark the point lightly, then re-read the pair before committing.
- Record each plotted pair in a short list so you can audit the sequence later.
Stroke breaks and connection order
A vertex list is not the same as a single continuous line. Stroke breaks tell you where to lift the pencil, and they usually mark a change of feature: an outline ending, a separate detail beginning, or a gap that should stay open. Connecting across a break closes a shape that was meant to remain open.
Work in the listed order rather than jumping to the most interesting part of the picture. Order preserves the intended construction, and it makes a missed point obvious: the next segment will not start where you expect. If a segment looks wrong, stop and re-check the two endpoints instead of adjusting the line by eye.
- Mark every stroke break in the list before drawing any segment.
- Plot all points for one stroke, then connect them in listed order.
- Lift the pencil at each break and begin the next stroke at its first point.
- Compare the finished stroke with the vertex list, not with memory.
- Leave breaks open unless the list explicitly continues the line.
Judging the result with a rubric
An original vertex sequence can be drawn with different line weights, and small spacing choices are legitimate. That means there is no single correct photograph of the answer. Judge the plot against criteria instead: are all points in the correct quadrant, are segments connected in the listed order, and are stroke breaks respected?
Separate plotting accuracy from presentation. A tidy picture with one swapped pair is still inaccurate; a rough picture with every point correct is still accurate. Note which criterion failed so the correction is specific rather than a general instruction to try again.
- Check quadrant placement for every point against the sign of each coordinate.
- Trace each segment and confirm both endpoints match the list.
- Confirm each stroke break appears as a gap.
- Mark presentation separately from coordinate accuracy.
- Correct only the failed criterion, then re-check the affected stroke.
Try this example
Plot the stroke (2,1) to (5,1) to (5,3), then a second stroke from (2,3) to (2,1). Describe the result and one check.
Show the worked explanation
Start at the origin. Move 2 right and 1 up to mark (2,1). Move 3 more right to (5,1), then 2 up to (5,3). Lift the pencil. For the second stroke, mark (2,3): 2 right and 3 up. Then mark (2,1), which is 2 right and 1 up. Connecting (2,3) to (2,1) gives a vertical left side. The two strokes form an open rectangle missing its top edge from (2,3) to (5,3). Check: the shared point (2,1) appears in both strokes and should be plotted once, and the gap along the top is intentional, not a missed segment.
Common mistakes
- Reading the vertical coordinate first because it feels like height. Point to the horizontal axis, say the first number, move, then say the second number and move vertically.
- Connecting the last point of one stroke to the first point of the next. Mark breaks in the list first, then lift the pencil at each break and restart at the next stroke's first point.
- Assuming a stretched-looking picture means the coordinates are wrong. Check whether horizontal and vertical grid spacing match before changing any plotted point.
Check your work
- Every ordered pair is plotted with the horizontal value read before the vertical value.
- Each point sits in the quadrant implied by the signs of its coordinates.
- Segments are connected in the listed order within each stroke.
- Every stroke break appears as an open gap rather than a joined line.
- Presentation quality is judged separately from coordinate accuracy.
Questions before you start
What if two points land on the same grid intersection?
That is valid. Plot the point once and note that the stroke passes through it twice; do not shift it to make the line look clearer.
Should I connect points with a ruler?
A ruler helps straight segments stay straight, but the priority is correct endpoints and correct order. Slight wobble does not change coordinate accuracy.
How do I check a point on an axis?
A point with a zero coordinate sits on an axis. Zero means no movement in that direction, so move only along the other axis.
