Commas to clarify meaning and avoid ambiguity
Use commas to clarify meaning or avoid ambiguity, including the comma before a name in direct address and the comma that keeps a list item separate from a description.
Board title: Commas that change meaning · Say it: “Today we're using one small comma to make sure our sentences say what we actually mean, so nobody ends up eating Nonna.”

Commas placed by feel, as decoration. Asked why a comma is there, they say it looks better or they needed a breath. By this stage that answer is not good enough. Every comma in this lesson has a job you can name in four words: it calls a person, or it keeps two things apart. If neither is true, it comes out.
Two words read as one item. Add ice cold water. Made with love bananas and ice. The comma is missing between an item and the thing that follows it, so the reader invents an ingredient. Ask how many things are in the jug and count them on fingers before deciding where the marks go.
No comma before a name they are speaking to. Let's eat Nonna. Drink up Sofia. Direct address is almost never taught explicitly, so children write it wrong for years without anyone naming it. Name it once, make it funny once, and it largely fixes itself, the comma before the name is the single most reliable win in the objective.
Unable to see the other reading in their own work. This is the hard one. They know what they meant, so the wrong meaning is invisible to them and only to them. The fix is structural, not moral: they swap sheets and read somebody else's sentence out loud, deliberately looking for the silly version. Nobody edits their own ambiguity well, including adults.
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.
