Mark off the extra information in this sentence with a pair of brackets. Brackets are the pair that whispers: what is inside is an extra the sentence can live without.

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.
Worked example: Where does a pair of commas go?
Worked example: This sentence needs a pair of commas around the extra information. Which version puts them in the right place?
Our science teacher asked Freya, the only pupil with a telescope, to explain the eclipse.
Our science teacher asked Freya the, only pupil with a telescope to, explain the eclipse.
Our science teacher asked Freya, the only pupil with a, telescope to explain the eclipse.
Our science teacher asked Freya the only pupil with a telescope to explain the eclipse.
Answer: Our science teacher asked Freya, the only pupil with a telescope, to explain the eclipse.
How you get there
Cover "the only pupil with a telescope" and what is left reads as an ordinary sentence, which is the test for extra information. So a pair of commas goes around exactly those words, opening before "the" and closing after "telescope". The version that reads "Our science teacher asked Freya the, only pupil with a telescope to, explain the eclipse." is wrong because the marks close one word too late, taking "to" inside them even though the sentence needs it.
Why the other answers tempt
Both marks of the pair have to move together; getting the opening one right is only half the job.
If they are stuck, say this
Find the words you could cover with your thumb and still read a whole sentence. The pair of marks goes around exactly those words and no others.
Mark off the extra information in this sentence with a pair of brackets. Brackets are the pair that whispers: what is inside is an extra the sentence can live without.
A parenthesis is an aside: drop it and the sentence is unharmed. "Scientists measured the whale at thirty metres." proves it. The pair of marks goes tight around the whole aside and nowhere else - one mark before "longer" and one after "field" - giving "Scientists measured the whale at thirty metres (longer than our school field)." Because the aside runs to the end, the closing bracket sits INSIDE the full stop: the full stop belongs to the sentence, not to the aside. A dash or a comma could not close it here at all, because there is nothing left to pair with.
What to say if they get stuck
Lift a run of words out. If the sentence still stands up on its own, that run is the extra bit.
The sentence works perfectly well as "Scientists measured the whale at thirty metres." - so everything you took out is the aside.
Open before "longer" and close after "field" - and the closing bracket goes INSIDE the full stop, not after it.

Mark one parenthetical interruption with a consistent punctuation pair. It is one of 41 named English skills in the 11+, in the punctuation strand, and this page carries 1 interactive exercise that practises it.
Both marks of the pair have to move together; getting the opening one right is only half the job. The wrong answers on this skill are built out of that, not out of random numbers, so it is worth naming out loud before your child meets it under time pressure.
Point at the next move rather than explaining the whole rule. Find the words you could cover with your thumb and still read a whole sentence. The pair of marks goes around exactly those words and no others.
The skill map draws the line here: Brackets, commas, and dashes are alternative forms, not interchangeable in every context. A question past that line is testing a different named English skill, which is worth knowing before you spend a week practising the wrong one.
The punctuation strand holds 9 skills that are tested together, and the pages next to punctuate parenthesis are use capital letters, mark possession and mark a sentence boundary. Each has its own exercise and its own link, and none of them needs an account.
Use Bracket Inserter, embedded on this page. It is the exercise the skill map attaches to punctuate parenthesis, 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.
Comprehension, vocabulary, grammar and punctuation are four different problems
A free diagnostic separates them, so practice goes where the gap actually is rather than on whichever one is easiest to set.
