Well, I pulled it out the other day and excitedly flipped to the one-syllable final /p/ words to use with Ava. It was new. It was colorful. It was a spiral bound book that stands up like an easel. It was new and shiny. I had high hopes. There were 20 one-syllable final /p/ words. They were easy to find, and Ava was interested. However, I was able to use only 8 of those. I was so disappointed. Let's take a look at why.
First I had to eliminate all the words with blends (CCVC). That eliminated 6 words (stop, sweep, clap, step, scope, and grape). Then I had to eliminate the 6 words that began with phonemes that were too difficult for her (cup, cap, chip, drape, cop, and rope). That left me with 8 (soap, type, ape, top, shop, ship, map, and soup).
Of those 8 words, two began with /s/ and two began with /sh/. If your client is having difficulty with those phonemes you would be left with only 4 words to work on.
(If I apply these same criteria to my own final /p/ card set I am able to use 24 of the 30 picture cards in the set. I have to eliminate the 4 that begin with /k/ and the 1 /l/ and the 1 /r/.)
I encountered similar problems with the other one-syllable words. If you are going to design a set of cards designed to target early emerging sounds, it is not actually helpful to have so many of the words include sounds that emerge late or words that include more complex syllable shapes.
I suppose the moral of the story is to try to get a good look at the actual word lists in the materials you are about to spend your limited resources on. It is definitely possible that when you get a good look at what is included the set may not meet your needs.

Try it for yourself. How many of these words would you actually be able to expect your child/client to produce accurately?
