This therapy material aims at helping children with articulation problems to master the correct production of problematic Arabic sounds. This is achieved by a gradual increase in the complexity of the sound environment. Each set contains 50 cards that represent the target sound in initial, medial, and final positions. In addition to sentences and questions and answers that contain the target sound with the purpose of facilitating smooth carry over for the target sound to everyday speech situations. This hierarchy in presenting the target sound is based on modern scientific articulation therapy techniques.
