There are 94 cards that can be used to practice the production of s-blend words orally or with reading. They can be used to focus at the word-level or at the sentence level. I made them in powerpoint so that I could print them in "handout" mode to be the size of smaller cards. They are easy to use with other groups of students at the same time to address other issues such as grammar, vocabulary, describing and answering questions.
Also, all of my cards have different colors/themes with a code at the bottom for a quick reference for therapists. These cards are also coded at the top for the specific s blend targeted. I have many sets of cards, so having them coded is key to staying organized. These are great for therapists who have to travel. I keep them in index card plastic boxes and label them with a sharpie.
