Matrix rule families

In pattern completion, check three rule types in order: constant addition or removal of elements, rotation or reflection of orientation, and attribute changes such as color, fill, size, or count.

Row-column consistency test

A candidate answer is correct only if its rule holds for every complete row and column of the matrix, not just the row or column containing the missing cell.

Overlay union rule

When matrix cells combine, union keeps every element from both cells; intersection keeps only elements present in both; difference keeps elements in one cell but not the other.

Rotation versus reflection

A rotated figure preserves the clockwise ordering of its features, while a reflected figure reverses that ordering. Track one asymmetric notch to tell them apart.

Diagonal pattern check

If row and column rules fail to explain a 3x3 matrix, test whether the main diagonal shares a constant attribute such as fill, size, or element count.

Count sequence rule

Matrix rows often follow an arithmetic count sequence (2, 3, 4) or a doubling sequence (1, 2, 4). Count small shapes per row to identify which applies.

Analogy structure

An analogy reads A is to B as C is to blank. The exact relationship from A to B must be applied identically to C to produce the correct answer.

Analogy change categories

Classify the A-to-B change as size change, rotation, reflection, color or fill inversion, part addition or removal, or position shift before applying it to C.

Compound analogy rule

At Level G, A to B may combine two operations, such as a 90-degree rotation plus a fill inversion. Both operations must be applied to C.

Reflection axis in analogies

When A to B is a reflection, identify the axis: horizontal, vertical, or diagonal. The same axis must be used for the C-to-answer transformation.

Rotation angle fidelity

If A to B rotates by a specific angle and direction, the C-to-answer step must use that same angle and direction. A mirror image is not an acceptable substitute.

Wrong-target distractor

A common wrong answer applies the A-to-B rule to A itself rather than to C, or applies only half of a compound rule. Check which figure was transformed.

Constant-step sequence

A serial sequence changes by a fixed step, such as adding one shape, rotating 90 degrees, or alternating colors. Find the step from consecutive figures.

Interleaved sequences

Alternating sequences use two rules: odd positions follow one rule and even positions follow another. Check each subsequence separately before predicting the next term.

Rotation step direction

Serial rotation steps are usually 45, 90, or 135 degrees. Track one asymmetric marker to determine whether the rotation is clockwise or counterclockwise.

Multiplicative growth

Some serial sequences grow multiplicatively (1, 2, 4, 8 elements) rather than additively. Test both growth models before choosing the next term.

Quadratic progression

If the step size changes by a constant amount (+1, +2, +3), the second difference is constant. Extrapolate using the pattern of differences.

Color cycle length

Fill sequences may alternate between two states or cycle through three. Determine the cycle length from the visible terms before predicting the next color.

Last-two-term verification

A valid serial rule must predict the last visible term from the one before it. A rule that fits only the first half of the sequence is likely wrong.

Mental rotation anchor

Track one distinctive feature, such as a corner, protrusion, or dot, through the rotation instead of rotating the whole figure at once.

90-degree clockwise rotation

A 90-degree clockwise rotation moves the top edge to the right side; 180 degrees moves top to bottom; 270 degrees clockwise moves top to the left.

Chirality test

A rotated shape can be superimposed on the original, but a reflected shape cannot without flipping. Use this to eliminate reflected answer choices.

Unfold in reverse order

In paper-folding problems, unfold in the reverse order of folding. Each unfold mirrors the hole pattern across the fold line, doubling the hole count.

Two folds, four layers

Folding a square in half twice creates four layers, so a single punch yields four holes arranged symmetrically about both fold lines.

Cube net opposite faces

On a cube net, opposite faces never share an edge. Count edge adjacencies to determine which faces can be adjacent when folded.

Figure combination rules

When figures combine, union keeps all parts, intersection keeps only the overlapping region, and subtraction removes the overlapping region from one figure.

Clockwise order check

For spatial options, note the clockwise order of three features. Rotation preserves clockwise order, while reflection reverses it, so this distinguishes the two.

Level G format

NNAT3 Level G is administered to students in grades 7 through 9 and uses four item types: pattern completion, reasoning by analogy, serial reasoning, and spatial visualization.

No reading required

The NNAT3 is a nonverbal reasoning test. Items use shapes and figures rather than words, so reading ability does not directly affect performance.

Answer elimination strategy

Eliminate choices that violate a confirmed rule, apply a rule to the wrong figure, or match only one attribute. Test remaining choices against all visible evidence.

Symmetry shortcut

Figures with a line of symmetry are unchanged by reflection across that line. Use symmetry to predict which reflections produce identical-looking results.

Attribute tracking table

For complex items, track each attribute separately: shape count, fill, size, orientation, and position. A rule may govern only one attribute at a time.
