A useful way to analyse a visual pattern is to name the change precisely. “It looks different” does not tell you what to predict. Rotation, reflection, movement and shading describe different kinds of change, and a question may combine them.
These are practice categories, not an exhaustive list or an official distribution of exam questions. The examples below are original and described fully in words so they do not depend on missing illustrations.
Rotation changes orientation
An arrow pointing up, then right, then down, then left makes successive quarter-turns clockwise. The next direction is up. A quarter-turn is 90 degrees; a half-turn is 180 degrees.
For a shape with rotational symmetry, some turns may look unchanged. A plain circle cannot reveal how far it has rotated. Look for a marker or asymmetric feature before claiming a direction of turn.
Reflection flips across a line
Imagine a square frame with a dot near its upper-left corner. Reflecting the frame's contents across a vertical line through the centre places the dot near the upper-right corner. Its height stays the same.
Reflecting across the horizontal centre line instead places it near the lower-left corner. Rotating it through 180 degrees places it near the lower-right corner. Tracking one off-centre marker helps distinguish these transformations.
Movement changes position
A dot may visit the top-left, top-right, bottom-right and bottom-left corners in order. Continuing that cycle returns it to the top-left.
The dot has moved around the frame. Unless another feature indicates orientation, saying the dot itself has “rotated” adds information that is not visible. Describe the property you can actually observe.
Counting and shading can act independently
Consider groups with one outline circle, two filled circles, three outline circles and four filled circles. A consistent continuation is five outline circles: the count rises by one, while shading alternates.
Check both rules across the whole sequence. Do not assume that every increasing count is a side-count rule, or that a colour change automatically means alternation; the frames must establish it.
Combination rules need evidence
Suppose a task defines the third frame as containing every symbol that appears in either of the first two, with duplicates shown once. If the first contains a circle and triangle, and the second a triangle and square, the third contains circle, triangle and square.
A different rule could retain only the shared symbol, giving triangle. Another could remove shared symbols, leaving circle and square. The instruction or completed examples must tell you which relationship applies. The word “combine” alone is not sufficient.
Avoid forcing one explanation
An odd-one-out question needs a defensible shared feature. A triangle differs from a circle, semicircle and quarter-circle in having only straight boundary segments, but other arrangements may support competing distinctions. Good practice questions make the intended criterion sufficiently clear.
Ask your child to state the rule and identify the evidence that could disprove it. If the rule changes for every frame, reconsider it. Return to the general approach for a practice routine, or compare visual patterns with numerical grids.
