Combining shapes is one of the standard non-verbal reasoning patterns in GL-style 11+ papers, and it is one of the most systematic. Two smaller shapes are shown, and your child must pick the single option that shows them merged, overlaid or joined together. NVR rewards method over talent more than any other 11+ subject — children who learn to interrogate each shape line by line routinely overtake 'naturally spatial' peers who rely on a first-glance guess. This guide gives you the exact method, the traps GL builds in on purpose, and free worksheets and timed mocks to drill the type until it feels automatic.
Where combining shapes sits in the NVR paper
GL Assessment now runs the 11+ Non-Verbal Reasoning paper across most selective regions, following CEM's withdrawal from separate 11+ testing around 2022–2023. NVR is one of four assessed areas alongside English, Maths and Verbal Reasoning, and in reasoning-heavy regions such as Lincolnshire it can carry roughly half the total marks. GL does not tell families in advance which question families will appear, so a confident child needs the whole toolkit. Combining shapes belongs to the spatial family, which sits next to these NVR relatives:
- Similarities / Most Like — find the shape that belongs with a given set.
- Most Unlike / Odd One Out — spot the shape that breaks the shared rule.
- Series / Sequences — continue a row of shapes by reading the pattern.
- Analogies — shape A is to B as C is to which option.
- Matrices — a grid with a missing cell governed by separate row and column rules.
- Rotations and Reflections — 90/180/270 turns versus mirror images.
- Codes, nets and cubes — decode a rule, or fold a 2D net into a 3D solid.
The four-step combining method
Teach your child to work the same way every single time. A repeatable routine beats inspiration under exam pressure.
- Name the two parts. Say what each shape is out loud — 'a triangle and a curved line' — so the brain holds them clearly.
- Overlay from an anchor point. Pick one fixed corner or edge and mentally slide the second shape onto the first from there. Ask: where do the outlines cross?
- Check for absences first. Eliminate any option with a missing intersection or a lost line segment. Additions are easier to fake than absences, so absences catch more wrong answers.
- Confirm the survivor. Only one option should keep every line from both shapes in the right place and the right size. Mark it and move on — do not re-argue a clean answer.
The visual attributes to scan
Almost every NVR question, combining shapes included, changes one or more of a short list of properties. Train your child to run this checklist like a pilot's pre-flight:
- Number of sides and corners
- Shading / fill (solid, striped, dotted, empty)
- Size and relative size between parts
- Orientation (which way it points)
- Position (inside, outside, overlapping)
- Line thickness and line style (solid vs dashed)
- Symmetry and any added or missing lines
- Count of small elements (dots, arrows, stars)
Common traps GL builds in
The wrong options — called distractors — are engineered, not random. The most common combining-shapes traps are:
- The lost segment. An option looks right but quietly drops one short line where the shapes overlap. This is why you check absences first.
- Wrong relative size. Both shapes are present but one is scaled up or down, so the proportions no longer match the originals.
- The extra line. A tempting option adds a line that was never in either starting shape.
- Rotation disguised as combination. One distractor shows the correct merge but rotated or mirrored — always confirm orientation matches.
- The red herring. A shading or dot change draws the eye away from the actual outline question. Focus on structure, not decoration.
Timing and pacing
GL NVR papers are multiple-choice with a separate answer sheet, usually run for around 50 minutes, which works out at roughly 35–50 seconds per question. Combining shapes is a 'do it or skip it' type: if the overlay has not resolved in about 40 seconds, mark your best elimination, flag the number, and return at the end. Practise the skip-and-return habit at home so it feels natural in the hall.
| Item | Typical figure |
|---|---|
| Paper length | ~50 minutes |
| Questions | ~60–80 |
| Target per question | 35–50 seconds |
| Combining-shapes budget | ~40 seconds, then skip |
How scores actually work
Raw NVR marks are converted into a Standardised Age Score (SAS), typically on a scale of about 69–141 with 100 as the average. The score is adjusted for your child's exact age in months, so a younger child in the year group is not disadvantaged. Many grammar schools look for around 111 or above, but exact qualifying marks vary by area and year, so treat any single figure with care. The practical takeaway: getting the harder spatial types right lifts the SAS meaningfully, which is why drilling combining shapes is time well spent.
How to practise this type
Work in short, focused bursts — ten questions, mark, then review every error out loud ('what property did I miss?'). Little and often beats long weekend marathons. Our free NVR worksheet sets isolate each pattern, the full NVR types list maps the whole territory, and timed mock papers knit the types back together at exam pace. When you are ready to see the full assessment picture, the GL paper guide and the revision hub show how NVR fits alongside English, Maths and Verbal Reasoning, and the 11+ process guide explains dates and registration.
Frequently asked questions
Does GL tell you which NVR types appear?
No. GL Assessment does not disclose in advance which question families will feature in a given paper, so children should be comfortable with the full spread — combining shapes, matrices, series, rotations, reflections, codes and nets.
How long is the NVR paper?
It is usually around 50 minutes and multiple-choice, with answers marked on a separate sheet. That gives roughly 35–50 seconds per question, so pace and the skip-and-return habit matter.
What score does my child need?
NVR marks feed into a Standardised Age Score, roughly 69–141 with 100 as average and age-adjusted for fairness. Many grammars want about 111+, but the exact pass mark depends on your region and the year, so check your local admissions details.
