We are making sure we have super sentences in year 3. We are making sure we ALWAYS start our sentences with a capital letter and end with a full stop or other appropriate punctuation.
Can you practise writing sentences at home making sure you from your letters correctly, start with a capital letter and read over your work to make sure it makes sense. You can try making your sentences more detailed by adding adjectives or conjunctions.
Here are some activity booklets for you to have a go at if you would like to.
