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.
Naming the fraction a bar shows
What fraction of bar A is shaded?
The whole bar is 9 parts, and 5 of them are shaded.
A bar cut into 9 equal parts, with 5 of them shaded.
Answer:
How you get there
Bar A is divided into 9 equal parts and 5 of them are shaded, so the fraction shaded is . The 4 unshaded parts are not the bottom number: the bottom number counts the whole bar.
Why the other answers tempt
Comparing the 5 shaded parts with the 4 unshaded ones gives , which compares two parts of the bar rather than a part with the whole.
If they are stuck, say this
Count every part the bar is divided into for the bottom number, then count only the shaded parts for the top one.
Slice the chocolate bar into 4 equal pieces, then shade 3 of them.
This engine’s own main skill is Equivalent Fractions. It practises identify a represented fraction alongside it.
Cutting every piece again multiplies how many pieces there are AND how many you shade, so the amount of chocolate never changes. , and are one single quantity wearing three different numbers. That is what "equivalent" means: different names, identical amount.
Step 1. Slice & shade. Slice the bar into equal pieces, then tap pieces to shade three quarters of it.
Step 2. The overlay. Lower the teal bar onto yours. Where does each shading stop?
What to say if they get stuck
Drag the CUTS slider until the bar falls into 4 equal pieces.
The bottom number says how many pieces the WHOLE is cut into. The top number says how many of them you take.
In step 2, lower the teal bar straight down onto yours and watch where each shading STOPS.
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 identify a represented fraction, the fix is the misunderstanding rather than more questions.
How identify a represented fraction differs from the skills beside it
The same exercise practises one other skill, and telling them apart is often the difficulty rather than the exercise itself. On this page the skill is: name the fraction represented by equal parts, and it stops where parts must form one equal-part whole.
Questions parents ask about identify a represented fraction
Answered from what the skill map records about this skill, not from a template. Every answer here is on the page, and the same questions are the page's FAQ structured data.
Name the fraction represented by equal parts. It is one of 55 named maths skills in the 11+, in the fractions, decimals and percentages strand, and this page carries 1 interactive exercise that practises it.
There is a specific mistake recorded against this skill: treats unequal parts as equal fractional parts. 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.
Point at the next move rather than explaining the whole rule. Count every part the bar is divided into for the bottom number, then count only the shaded parts for the top one.
The skill map draws the line here: Parts must form one equal-part whole. 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.
The fractions, decimals and percentages strand holds 9 skills that are tested together, and the pages next to identify a represented fraction are locate an equivalent value, multiply fractions and recognise equivalent fractions. Each has its own exercise and its own link, and none of them needs an account.
Use Fraction Slicer, embedded on this page. It is the exercise the skill map attaches to identify a represented fraction, it runs in the browser with no account to make, nothing is scored, and nothing a child does here is recorded or sent anywhere. It also has its own link, so you can send it to a child without sending them anywhere else first.
