Capital Letters and Full Stops Worksheet (Free KS1 Punctuation)

What this worksheet teaches

By the end of Year 1, children are expected to begin punctuating sentences using a capital letter and a full stop. This worksheet isolates that single skill so it does not get lost among other demands. In the first task, children copy or rewrite short, familiar sentences, supplying the capital letter the sentence is missing at the start and the full stop it is missing at the end. In the second task, they compare two versions of the same sentence and tick the one that is correctly punctuated. Reading the sentence aloud and pausing where the full stop belongs is the most reliable strategy at this age, because punctuation is closely tied to the natural rhythm of speech.

How to use it at home or in class

Begin with the colouring picture: it lowers the stakes and gives reluctant writers a calm start. Then read each sentence in the first task aloud together, asking the child to point to the very first letter and the very last word before they make a mark. Encourage them to say "big letter to start, full stop to finish" as a memorable rule of thumb. For the ticking task, ask the child to explain why the version they chose is correct, as putting the reasoning into words deepens the learning far more than the tick itself. Keep sessions short and praise effort; this skill is built through frequent, low-pressure repetition rather than long bursts.

Common difficulties and how to support them

Two errors are very common at this stage. The first is the missing or mid-sentence capital letter, often because children are still learning which letters look different in their capital form (such as a, e and r). Practising forming capitals separately, away from the punctuation task, can help. The second is the omitted full stop, especially when a child runs several ideas together. Pausing for breath while reading aloud highlights where each sentence should end. It is also worth gently noting that names of people and places need a capital letter too, though full mastery of that comes a little later in Key Stage 1.

What comes next

Once a child can reliably start a sentence with a capital letter and end it with a full stop, the natural next steps are using a capital letter for the personal pronoun 'I' and for proper nouns such as days of the week and people's names, and then meeting the question mark and exclamation mark. In Year 2, children begin to use these alongside commas in lists. Keeping early sentence demarcation secure makes all of this later punctuation work far smoother, so it is well worth returning to a sheet like this whenever a refresher is helpful.
