Colourful Semantics is an approach created by Alison Bryan, Speech and Language Therapist based in the UK. This has been particularly effective for teaching children with a variety of Speech, Language and Communication Needs such as autism and developmental delays to name a few. It provides a more engaging experience for children as they learn! 
 
The use of colourful semantics is helpful in: 
Encouraging wider use of vocabulary
Increasing lengths of sentences
Supporting children in answering questions 
Developing their use of nouns, verbs, prepositions and adjectives
Improving narrative skills 
and so much more...
