These cards include pictures and phrases which have initial /s/ words in them. They can be used to drill students or in between an activity. You can drill at the word level or phrase level. I often will print them out for parents to take home as homework. They are also useful when working with a group of students that have different objectives. Since there are pictures, you can tailor questions to almost any student's goals. They are color coded and also have the targeted skill posted on the bottom left corner.
