It's broken
Didn't like
I also didn't like that the individual sounds were produced with the schwa after it - this makes it confusing for children as they tend to put the schwa in the word. For example- sound "t" produced in isolation "tuh". Put in word "tap" becomes "tuh-ap". Sounds in isolation should be strictly the sound -no schwa.
I like the idea and activities.
G'day and こんにちは!
