It is important to encourage children to recognise and pursue the areas in which they excel (do more of what they enjoy) and support them with the areas they find difficult.
Allow children to use a word processor to complete some written tasks. This highlights spelling errors and offers alternatives. If they can’t type, encourage them to learn, so that they are able to use a Word Processor with more speed and fluency.
Play games to support memory and retention e.g. pairs, Go Fish etc. (see resource links for more ideas)
Enable children to access age related audio books to develop a love of reading. Encourage (don't force or push) them to share what's happening in the story and share their excitement, wondering aloud what will happen next. This will develop their vocabulary and comprehension, without them even realising that they are learning.
Don’t make reading a fight. Encourage chn to read one page and you read the next page. Read some books to them for pleasure and invite them to read a section if they want to (don’t push if they don’t want to). By developing a love of books and stories children will naturally want to learn how to read, so make the experience as pleasurable as you can.
