A vocabulary chart is useful tool to use to get children started with literacy, especially those who have previously experienced trouble learning to read and write.  Use it as a crutch to get that initial breakthrough and discard it as soon as it becomes apparent that it isn't needed any more. 

Build the word chart with the child, beginning with what he/she already knows.  The whole purpose of a word chart is to prove to the child that they can read and recall many words easily.  By repeatedly reading the words
in their place the reader becomes confident in their knowledge and proud of their expanding vocabulary.  Words that are related are grouped together, as well as words that are easily confused.  Similarities and differences can be highlighted, and memory triggers such as colours, or position are highlighted.    Not only is it a record of what they know, but it can be a record of their progress or growth too, because you can easily total the number known each day. 

Add the most important words first, such as Corey, Mum, Dad, Tim, Suzy, and Silky.  These are easy to learn by reading them from the list with children remembering them firstly by their position.  Numbers and colours are also easy to learn.  Words of special significance should go in their own boxes so that they are remembered by where they are.  Gradually build up the vocabulary as you see the child needing a word or trying to use it in writing, or when they read new words.

Use the chart daily to practice reading the words as fast as possible and to add any new words found.  Play 'find the word' games to break up the session.  Try making up oral sentences from the words.  Take words from the chart to make up other games for practice and rehearsal.  Most importantly, display it for the child to use when writing, especially if there has been a reluctance to write in the past.  Although they will rely on it initially, they will soon become confident to fly alone if you encourage them to write new words and support their invented spellings.
