The Difference Between Vowels and Consonants
A method to help pupils gain a full, conceptual understanding of the difference between vowels and consonants. This is done by defining these terms through a representation of the human articulatory mechanism. Pupils are encouraged to feel how the various articulators move when producing sounds. They are then asked to contrast the production of vowels v. consonants. This leads to the realisation that vowels are strictly necessary in every syllable in every word because of the unobstructed nature of their production.
