Read this 'sentence'.
We went to the park we played on the swings we had a good time.
It is hard to read because it is really three separate sentences. The first one tells us that the children went to the park, the second one tells us that they played on the swings and the third one tells us that they had a good time.
If we split the writing into three sentences using full stops and capital letters it is much easier to read.
We went to the park. We played on the swings. We had a good time.
In this worksheet you can practise splitting writing up into sentences to make it easier to read.
