Common areas of difficulty on the 11 plus exam

1. Maths: algebra

Algebra is covered in Year 6 as part of the national curriculum. Your child will be taught to:

  • Use simple formulae
  • Generate and describe linear number sequences
  • Express missing number problems algebraically
  • Find pairs of numbers that satisfy an equation with two unknown numbers

But as 11 plus exams happen at the start of Year 6, your child is unlikely to have spent much, if any, time on algebra in the classroom yet. During Year 5, it’s a good idea to help your child gain a firm understanding of key algebra subtopics at home, followed by exploring learning beyond the foundations of algebra.

As a bonus, this will give them a head start in a topic that will form an increasing part of the maths curriculum they’ll encounter at secondary school, up to GCSE and beyond.

2. Non-verbal reasoning: following folds

The ability to solve non-verbal reasoning questions like the one below come naturally to some people. However, for many, it is a topic that can prevent them from gaining a top score. Children can sometimes be tripped up if they are unfamiliar with this style of question, so introducing your child to spatial reasoning practice early is key. Just like learning to tie your shoelaces, practice makes perfect – once the logic clicks, it will make sense.

3. English reading comprehension: inference

When it comes to comprehension, ‘inference’ tends to be among the trickiest subtopics. It requires students to form conclusions based on contextual evidence from the text, like in the example below.

A great way to boost your child's inference skills is by encouraging them to read widely. Reading a variety of types of text for pleasure will broaden their vocabulary and enhance their analytical thinking. Get tips and free resources for engaging your child with reading here.
When reading together, a fun way to build inference skills is to play ‘prediction’ and ‘storytelling’ games. At the end of a chapter get your child to write down a prediction of what is going to happen next. Another version of this game is to write an alternative ending to a story!
We also recommend students join the fun Comprehension Challenge Live Lessons (or watch the recordings in the Lesson Library) to build both inference and deduction skills.

4. Maths: worded problems

Worded problems are infamous for costing children marks on 11 plus maths papers. Often, the last sentence switches what you think the question is asking you, like in the example below.

To build confidence with solving worded problems, have your child complete practice questions in this style, then talk through their answers together. Ask them to explain their thought process to you. Over time, your child will become comfortable with converting worded questions into numerical sums.

Encourage your child to always take the time to read the question carefully, and it will become habit. This will make them less likely to be caught out by surprising wording in the real exam – and more likely to pick up marks where most of their peers are dropping them.

For Atom Nucleus subscribers, we recommend setting regular Custom Practices in the 'Weights and Measures' subtopic of maths. This will present your child with time, speed and money questions which are often displayed as worded problems.
Once your child has completed each activity, go through the transcript together, reflecting on any corrections and what they would do differently next time. If your child spots that they didn’t read the question properly, they are far less likely to make the same mistake in the real exam!

5. Non-verbal reasoning: nets and cubes

Another of non-verbal reasoning’s stickiest areas, questions involving nets and cubes continue to prove one of the areas that children struggle with most.

On the 11 plus, your child is likely to see two types of nets and cubes questions:

  • Identify which cube can be formed from the given net
  • Identify which net would form the given cube

The key is to help your child gain a solid understanding of how the 2D nets translate to 3D cubes. Helping your child begin to visualise the nets and cubes as real-world entities will aid tremendously in their ability to answer the questions. Giving your child a real-life object like a dice or Rubik's Cube is a helpful way to support their visualisation when practising this subtopic.

We also recommend watching the 11 Plus Non-Verbal Reasoning: Nets and Cubes Live Lesson recording. Your child will learn all about the dud rule, opposite rule and orientation rule. Combined, these rules will help your child face any nets and cubes questions that may come up on the 11 plus!
