Find the Error 50 < Check It Again! Index (Extract adapted from an article in a national magazine for teachers)   What kind of mistake do you see? (Choose one:) apostrophes articles doesn't make sense punctuation singular / plural spelling                               Answer: punctuation The punctuation mistake comes in the second to last sentence, which starts 'Above all …' The problem is with the comma, which has been put in the wrong place. It should be used to separate the two clauses: 'Above all …' and the rest of the sentence, so that the sentence should read: 'Above all, this means that many teachers have had to …' Commas are helpful in sentences because they separate clauses, making what is written easier to read. Imagine a comma as half a pause and a full stop as a full pause. Now read this sentence aloud, leaving half a pause where the comma is: 'Above all this, means that many teachers have had to go 'back to school' themselves…' It doesn't sound right, does it? Now read it aloud again, with the comma after 'Above all' instead of 'this'. It should sound much better this time. Click here to download this page as a free .PDF worksheet
