Colons to introduce a list; semi-colons within a list
Use a colon to introduce a list after a complete sentence, and use semi-colons to separate items in a list that already contains commas.
Board title: Colons and list semicolons · Say it: “Today we're using a colon to introduce a list, with a whole sentence in front of it, and semicolons to keep the long items apart.”

A colon after half a sentence, in a list that runs across the page. The ingredients are: mango, ice and lime. This is the one that survives into secondary school, because it looks like every recipe book they have ever seen. Cover the list with a hand: The ingredients are cannot stand alone, so the colon goes. Either drop the colon, or rewrite the front so it is a sentence, You will need three things: and then the list. Bulleted lists are the one exception: there the stem may stop halfway (see Every Line the Same).
Colon and semi-colon treated as the same mark. Bring these; a glass, a straw and ice. They know both are 'bigger than a comma' and choose by look. Give them the two verbs and make them say which one they need: introduce, or separate. Nothing else distinguishes the marks in this objective.
Semi-colons sprinkled over short lists. Mix ice; lime; soda. Having just met the mark, they use it everywhere, and it reads as though the writer is trying to impress. The semi-colon earns its place only when the items already contain commas. If the commas are coping, leave them alone.
A capital letter after the colon, or a heading mistaken for a sentence. You will need: Ice, lime and soda. A list after a colon carries on in lower case unless the item is a name. And a label on a recipe card, Ingredients:, is a heading, not prose; it is fine on the card and wrong in the middle of a paragraph. Show both and name the difference, or they will quote the card back at you.
Same four tasks on every sheet, in the same order, with the same look. Only the demand changes. Print the one each child needs; nobody does two.
Same four tasks as every other sheet, same order, same look, the demand is lower, not the dignity. Shorter passage in Task 2, and in Task 3 a word bank or words to tick, with printed sentence starters. Give it to anyone who needs a way in, and expect them to move up.
The core sheet. Give this to most of the class. No word bank; in Task 3 pupils choose from a few close options, then use one in a sentence of their own.
Same four tasks, more demand, a longer passage with a subtler error, and Task 3 asks for two things at once. Not extra work; harder work. Nobody should be doing Spicy and the Medium sheet.
