This is an interactive tool for use with younger students, or any student struggling to isolate vowel sounds. The presentation looks nice and is extremely interactive. The students are able to click on sound buttons to listen to the teacher model the sound. They can then practice discerning between the sounds until they master each vowel. Students are able to choose which letters to work on, allowing for ownership and choice. There are a few glitches with the sound. See the technical remarks.
When I click the sound button on slide 6, it returns me to the short a page rather than playing the sound. This same thing happened on slides 13, 20, 27, and 34. Also, the sound buttons for the "Stretch", "Swap", and "Review" activities are visible, but I cannot click on them. This may cause confusion for such a young student.
