This audio CD correlates to the Delta ESL Phonics Student Book Level 4. The audio CD is fully integrated with all of the listening sections in each unit and the final level test, as well. It helps students build phonemic awareness and develop their aural tracking skills as they practice identifying sounds with their written symbols and visual pictures. Students learn to recognize, identify, and discriminate various sounds and sound clusters and hear the language as they are learning to read it. The CD also provides the aural input for various puzzles and games throughout each book.
