I don't know where I was complaining about the pictures on SLP program websites, but here is another example. I can only imagine the one on the right is supposed to be teaching the one on the left to produce /m/, but what the heck is with the card?
Is the one on the right intentionally tilting back her head to produce /m/?
I particularly like this one for some reason, although now that I have been paying more attention, I notice that many of these show ladies holding up letters, and I cannot imagine any speech therapist buying wooden letters like this, especially since we don't target letters, but phonemes:
Would she have CH, SH, TH, and TH or just hold up two big letters while still using their finger to say "You make sounds with this part of your body?"
I have never shown my clients /ð/ and /θ/, but you don't mix and match until they are ready for it.
