Commas to avoid ambiguity

Use commas to clarify meaning and avoid ambiguity in sentences where the absence of a comma could cause misreading

How to tell they’ve got it

Tick these off as you see them — no test required.

Insert a comma to prevent ambiguity, e.g. 'Let's eat, Grandma' vs 'Let's eat Grandma' or 'Most of the time, travellers worry about their bags'
Identify sentences where a missing comma changes the meaning and explain the two possible readings
Use commas after introductory elements (adverbial phrases, subordinate clauses) to prevent misreading of the main clause

Try this together

Can your child explain why "Let's eat, Grandma" and "Let's eat Grandma" mean very different things — and use that kind of comma in their own writing to avoid confusion?
