For dyslexic children who find telling the time a difficult task, keep to the x minutes past y o'clock expression for some period of weeks during which time constantly use and practice the usefullness of reading the clock. This is where the action takes place. Finally fill in the end box. Then speak the story following the notes. Then write it.
Mind mapping can take many forms.
A 'spider diagram' with a central topic with lines out to sub-headings leading onto further branches relating to them. A sheet of paper with words jotted down in random then circled and numbered once the brainstorming period has ended. Another way is to start by drawing a picture. If a child has an idea for story or is required to express an event in their own words, they can draw one or more illustrations first to support the prompting and collation of ideas without being impinged upon by the written word.
