Series (what comes next) is one of the standard non-verbal reasoning patterns in GL-style 11+ papers. A row of shapes changes step by step, and your child must pick the box that continues the sequence. NVR rewards method over talent more than any other 11+ subject: children who learn to interrogate shapes systematically routinely overtake 'naturally spatial' peers who guess. This guide gives you a repeatable method, the traps that catch the most marks, a concrete timing budget, and free practice tied to this exact question type.
What the question looks like
You are shown four or five boxes in a row. Something changes from one box to the next, and one box at the end (or occasionally in the middle) is missing. Below sits a set of five options labelled A to E, and only one continues every rule at once. In the GL format the answer is marked on a separate multiple-choice answer sheet, so children never write on the question booklet itself. Expect several series questions in a paper, and in reasoning-heavy regions the NVR score can carry a large share of the total standardised marks, so this is not a type to skip.
Series belongs to the wider family of NVR patterns alongside matrices, analogies, rotations, reflections, codes and nets. Series is the one that trains the core habit the whole paper depends on: watching several properties change together, step by step, without losing track of any single one.
The properties to scan every time
Almost every series is built by changing one or more visual attributes at a steady rate. Teach your child to run down this checklist for each box before deciding anything:
- Number of elements — do dots, lines or small shapes increase or decrease by a fixed amount each step?
- Shading and fill — black, white, striped, dotted; does it alternate or rotate through a set order?
- Size — is the main shape growing or shrinking box to box?
- Orientation — is an arrow or shape rotating a fixed amount (often 45 or 90 degrees) each step?
- Position — is an element moving around the box, for example one corner clockwise per step?
- Line thickness and style — thin to thick, solid to dashed.
- Shape identity — do the shapes themselves cycle through a repeating list?
The method, step by step
The reliable approach is to separate the moving parts and describe each in one word, rather than trying to see the whole picture at once:
- Split the box into elements. Name the big shape, the small shape, the shading and any dots or lines as separate things.
- Track one element across all boxes. Ignore everything else and follow just the shading, say, left to right. Note it in one word: "alternates" or "rotates" or "grows".
- Repeat for the next element. Now follow only the arrow's direction, then only the number of dots. Each gets its own one-word rule.
- Apply every rule one more step. Predict what the missing box must contain for each element before you look at the options.
- Match your prediction to the answers. Eliminate any option that breaks even one rule. The correct answer satisfies all of them simultaneously.
Predicting the answer before reading the options is the single most valuable habit here. Children who look at the five choices first get pulled towards a plausible-looking distractor and stop checking.
The classic traps
Most lost marks come from a small set of predictable mistakes:
- Following only the eye-catching element. The big rotating arrow is obvious; the quietly growing count of dots is the one being tested. Always finish the whole checklist.
- Missing a second simultaneous change. Two properties often move on different cycles — shading alternating every box while a shape rotates every box. Getting one right and one wrong still scores zero.
- Confusing rotation with reflection. A shape turned 180 degrees can look like a mirror image but is not. Ask "did it spin or did it flip?"
- Red-herring detail. A distractor may match the last box perfectly but ignore the direction of change. Continue the pattern; do not copy the previous box.
A sensible timing budget
GL NVR papers are tightly timed, so speed matters as much as accuracy. Use this as a rough planning guide and adjust to your child's real paper:
| Measure | Typical figure |
|---|---|
| Paper length | around 50 minutes |
| Questions | roughly 60–80 |
| Time per question | about 35–50 seconds |
| Pacing rule | skip after ~45 seconds, mark it, return at the end |
The skip-and-return habit protects the easy marks further down the paper that a stuck child never reaches. A printable pacing card by the desk turns this into a reflex.
How the marks become a score
GL converts the raw number correct into a Standardised Age Score (SAS), roughly on a 70–140 scale where 100 is average. The score is adjusted for your child's exact age in months, so a summer-born child is not disadvantaged against an older classmate. Because harder items lift the standardised score, getting the two-change series questions right — not just the single-change ones — is where a good NVR mark is really won. Exact qualifying scores vary by area and year, so treat any single "pass mark" you hear as local guidance rather than a fixed national number.
How to practise this type
Do series in short, focused bursts — ten questions, mark, then review every error out loud: "what property did I miss?" That spoken review is what converts practice into progress. Our free NVR worksheet sets isolate each pattern so your child drills one skill at a time, the full NVR types list maps the whole territory, and timed mock papers knit the types back together at genuine exam pace. When you are ready to see where your child sits, the centre-specific mocks mirror the format used by your target schools, and the revision hub sequences everything from Year 4 foundations to Year 6 timed refinement.

Frequently asked questions
How many marks does series carry?
GL does not publish a fixed breakdown, and it never tells you in advance which pattern types will appear. Series shows up in most NVR papers alongside matrices, analogies and rotations, so it is always worth mastering.
How long is the NVR paper?
Around 50 minutes for roughly 60–80 questions, which works out to about 35–50 seconds per question. Practising against a timer is essential; check your target school's format on the grammar school directory.
What score does my child need?
Scores are reported as a Standardised Age Score, usually on a 70–140 scale with 100 as average. Qualifying marks differ by region and year, so use local figures rather than a single national number.
