NVR Series Completion: Strategies for the 11 Plus
Key Takeaways
- Series questions follow a linear pattern that children must extend.
- Compare adjacent pairs to isolate changes systematically.
- Common patterns include rotation, alternation, addition, and shading.
- Spend no more than 45 seconds per question in the exam.
Series completion is one of the most common non-verbal reasoning question types in the 11 plus. Children are shown a sequence of figures that follow a pattern and must identify what comes next from a set of answer options. Unlike matrices which require two-directional thinking, series questions follow a single linear progression. This makes them more accessible, but the patterns can still be complex, involving multiple simultaneous changes across the sequence. This guide teaches your child a reliable method for solving series questions and covers the most common pattern types they will encounter. EdifyPod Nexus includes extensive series completion practice across all difficulty levels.
NVR series completion questions show a sequence of figures following a pattern. Children identify the rule by comparing adjacent pairs and select the next figure. Common patterns include rotation, alternating elements, cumulative addition, and progressive shading. The pair comparison method is the most reliable solving strategy.
How Series Questions Work
A series presents three to five figures in a row. Each figure differs from the previous one according to a consistent rule. The child must identify the rule and apply it to determine the next figure in the sequence.
The simplest series involve a single change, for example, a shape that rotates 45 degrees clockwise in each step. More complex series involve multiple simultaneous changes: the shape rotates AND changes shading AND a new element is added at each step.
Children who approach series questions by looking at the whole sequence at once often feel overwhelmed. A more effective strategy is to compare adjacent pairs, figure one to figure two, then figure two to figure three, to isolate each individual change.
The Pair Comparison Method
Teach your child to compare the first two figures in the series. Ask systematic questions: what is the same? What is different? Has anything moved, rotated, changed colour, changed size, appeared, or disappeared?
Once changes between the first pair are identified, check whether the same changes occur between the second and third pair. If they do, the rule is confirmed. If not, look more carefully, the pattern might alternate or follow a cycle.
This method works because it reduces the cognitive load. Instead of trying to understand five figures simultaneously, the child focuses on just two at a time. Once the rule is confirmed, applying it to find the next figure is straightforward.
Common Series Patterns
The most frequently tested series patterns include progressive rotation (each figure rotates by a fixed angle), alternating elements (shapes alternate between two or three states), cumulative addition (one more element is added each step), progressive shading (white to striped to grey to black), and positional movement (an element moves around a grid in a consistent direction).
Some series combine two or more of these patterns. For example, a triangle might rotate 90 degrees clockwise while its shading alternates between white and black. Children must identify both rules to choose the correct answer.
Exposure to all these pattern types is essential. The more types your child has encountered, the faster they will recognise new instances in the exam.
Practice Tips for Series Questions
Start with single-change series to build confidence with the pair comparison method. Once your child can solve these reliably, introduce two-change and three-change series.
Time pressure is a factor in the exam. Encourage your child to spend no more than thirty to forty-five seconds per series question. If they cannot identify the pattern quickly, they should make their best guess and move on, spending too long on one question costs marks elsewhere.
When reviewing practice answers, focus on the method rather than just whether the answer was correct. A child who identified two of three changes but missed one is making good progress and needs only minor adjustment.

Frequently Asked Questions
How many changes should my child expect in a series question?
Simple questions involve one change. More challenging questions involve two or three simultaneous changes. Exam papers typically include a mix of difficulty levels.
Are series questions the same in GL and CEM papers?
The concept is the same but the presentation may differ. GL papers typically show the series with labelled answer options. CEM integrates them into longer timed sections.
My child keeps getting series questions wrong. What should we do?
Go back to basics with the pair comparison method. Practise with single-change series until the method is automatic, then gradually increase complexity.
