Your child's school should let you know which tricky words your child is learning to read and write. However, if you haven't received this information, this section of the website should give you a useful guide (although words do vary according to the phonics programme used by each school). Your child may also be working at a faster/slower pace than that indicated so pick the section that is appropriate for his/her needs by moving forwards or backwards a term at a time:
oh, their, people, Mr, Mrs, looked, called, asked
A YouTube video the children can sing and move to. Useful for the 'teach' part of the lesson on the day you introduce the spelling of this tricky word. Thereafter useful in the 'revisit and review' part of the lesson.
A whiteboard with letters of the alphabet along the bottom. Call out a tricky word your child needs to practise writing. Then he/she clicks on the letters to make the word appear on the whiteboard.
From ictgames.com. A set of single letter graphemes and digraphs which, when pressed, are fired from a cannon (just ignore the graphemes that haven't been introduced at this stage). They can then be dragged onto the water to make tricky words (this will mostly involve using the letters on the left hand side, as if they were magnetic letters).
Below are links to a variety of creative trays you can make and use with your child to help him/her learn to write tricky words. Select one that links to your child's interests or the current time of year, as this should motivate him/her to write. Call out a tricky word your child needs to practise and ask him/her to write it in the tray.
