CONCLUSION: SHORT VOWELS VS LONG VOWELS.

  Short vowels and long vowels can be identified in some ways. First, it can be recognized according the stress they have. A word ending with a consonant that is voiced is longer, but if the word ends with a consonant that is voiceless it will be shorter. For example: in the words "cat" and "cab", the first one is shorter and the other is longer. Second, we can find the difference between them by knowing how the word is written. For example: the long vowels can be identified if the majority of words have two vowels like in "sheep". And the short vowels can be identified in the majority of the words are written with only a vowel, like in "ship". In conclusion, the different stress and the way the words are written help us as future teachers give some tricks that students can follow and don't make the same mistakes. Students can also be provided the charts that the short and long vowels are placed. It will help them to analyze between the different pronunciations the English vowels have.
Here we have a video where you can teach children about the short and long vowels.
