The purpose of the activity is to target minimal pairs. We talk about trains and how each one has a special car that always rides on the end: the caboose. Then I explain that some words have a special "caboose sound" too. If we forget the caboose sound, people might think we are talking about something else.
There are two sets of cards. Train Cards carry words that have caboose sounds...
There are other variations for the cards. Sometimes we work on auditory discrimination where I say the words and the student guesses whether they heard the "train" word or the "coal" word.
What language do you use to talk about final consonant deletion with little ones?
