Commas in Clauses and Lists Worksheets — KS2
Commas are the most versatile punctuation mark in English, and the National Curriculum introduces their different uses progressively across KS2. By Year 6, children must be able to use commas to separate items in a list, after fronted adverbials, in relative clauses, and to avoid ambiguity. Our commas worksheets introduce each use separately before combining them in more complex writing activities.

Key Skills Covered
The Four KS2 Uses of Commas
Commas in lists (Year 3): We need milk, bread, eggs, and butter. After fronted adverbials (Year 4): On Tuesday morning, we visited the museum. In relative clauses (Year 5): My teacher, who has worked here for ten years, is retiring. To avoid ambiguity (Year 6): Let's eat, Grandma! vs Let's eat Grandma! Our worksheets address each use with explicit instruction before practice.
Commas vs Full Stops: The Comma Splice
A common KS2 error is the comma splice — joining two main clauses with only a comma: "I went to the shop, I bought some milk." This should be two sentences, or the comma should be replaced with a conjunction (and, but, so) or a semicolon. Our worksheets identify comma splices as a separate activity, helping children recognise and correct this error in their own writing.
