Tricky words are difficult to decode. We use them often, and children encounter them early in decodable books, so reading them fluently is important. Words will be added to each child's tin once they have been introduced at school. 

Please practise these at home. You can turn it into a game such as finding the word 'full' and running it back to you, or writing words in chalk outside and squirting them with a water pistol.
