Sentences

I have been learning about sentences. When we write a story, we use simple sentences, compound sentences and complex sentences. 

- Simple sentences tell 1 thing eg I am a girl. A simple sentence starts with a capital letter and ends with a fullstop.

- A compound sentence tells 2 things - I am a girl and I am 9 years old. In the middle of the 2 things is a joining word - and, but, so then or because. A compound sentence also starts with a capital letter and ends with a fullstop.
