A sentence need to make sense.
Look at these words:
cat drank milk its the
They don't make sense like this, but if we swap them around and add a capital letter and a full stop we get a proper sentence.
The cat drank its milk.
This now tells us what we see in the picture and makes sense.
We need to use a capital letter for the first letter of the first word of each sentence.
In this example, the first word is 'the' and the first letter is 't' which needs to be the capital letter.
The full stop comes after the last word.
In this example, the last word is 'milk', so the full stop goes after the word 'milk'.
This activity provides practice for identifying which sentence makes sense.
