What does a child have to do to decode a pictogram key in the 11+?

Use a pictogram key to determine one represented quantity. It is one of 55 named maths skills in the 11+, in the data strand, and this page carries 1 interactive exercise that practises it.

Why does my child keep getting decode a pictogram key questions wrong?

There is a specific mistake recorded against this skill: counts symbols without multiplying by the key. 11+ papers are written to offer exactly that answer, so a child can be confident and still lose the mark. When it keeps happening, the fix is the misunderstanding rather than more questions.

What can I say if my child is stuck on decode a pictogram key?

Point at the next move rather than explaining the whole rule. Count the icons in the Rockets row and multiply by 2; a half icon is worth 1, not the full 2.

What is not part of decode a pictogram key in the 11+?

The skill map draws the line here: Includes fractional symbols only when stated by the key. A question past that line is testing a different named maths skill, which is worth knowing before you spend a week practising the wrong one.

A worked example

One question of the kind this skill is tested with, worked all the way through: the reasoning, and what the wrong answers are there to catch.

Topics chosen by children for the space project

Start with the Rockets row. How many children does it stand for?

Each icon stands for 2 children, so a half icon stands for 1.

🚀 = 2

Comets

Rockets

Galaxies

Meteors

Answer: 7

How you get there

The Rockets row draws 3 whole icons and a half icon, and the key says one icon stands for 2 children, which means the row is worth 7 children altogether.

Why the other answers tempt

Each icon is worth more than one, so the number of icons is never the answer on its own.

If they are stuck, say this

Count the icons in the Rockets row and multiply by 2; a half icon is worth 1, not the full 2.

Ready? Let's try Decode a pictogram key together. Take a look at the picture. Here is what matters: Each icon stands for 2 children, so a half icon stands for 1. Pictogram where each 🚀 means 2. Rows: Comets is 13; Rockets is 7; Galaxies is 6; Meteors is 11. Here comes the question: Start with the Rockets row. How many children does it stand for? A handy clue is: Count the icons in the Rockets row and multiply by 2; a half icon is worth 1, not the full 2. Nice work. Here is the thinking: The Rockets row draws 3 whole icons and a half icon, and the key says one icon stands for 2 children, which means the row is worth 7 children altogether. So our answer is: 7. One sneaky trap is: Each icon is worth more than one, so the number of icons is never the answer on its own. Can you show me the first move in your own words? No rush; one calm step is enough.

What this exercise is doing

Pictogram Reader

Tap the Adventure row. Then use the key to say how many books it stands for.

The Adventure row draws 2 and a half pictures, and the key says each whole picture stands for 2, so the row stands for 5. Counting the pictures and stopping gives 2, which is the answer to a different question: a pictogram is drawn small on purpose, and the key is what turns what you can count into what it means. A part picture is worth part of the key, not a whole one.

Step 1. Find it. Tap the row the question names.
Step 2. Read it. Now use the key to choose how many books that is.

What to say if they get stuck

Find the bar, row or slice the question names before you read anything. Getting the label right matters as much as the reading.
The scale does not always count up in single steps. Work out what a single line is worth before you read anything off it.
Keep your finger level as you slide from the board across to the scale. Drifting up or down by a line is the commonest slip there is.

What usually goes wrong here

Counts symbols without multiplying by the key.

This is the wrong answer 11+ papers are built to offer, so it is worth watching for directly: a child who does this will look confident and still lose the mark. If it keeps happening on decode a pictogram key, the fix is the misunderstanding rather than more questions.
