I've been using this for some time with several different students. It's updated regularly which is good but also means you have to have the latest edition. I have bought the wrong edition by mistake before so always check the edition.
This will be the first time for me to use these materials chosen for a short 2-week children's ESL summer "enrichment" course. The student book is well-laid out. Although the chants seem a little drab, I believe that they will provide the necessary repetition of structure and intonation. I really like the teacher's edition! Lots of additional activities and black-line masters in the back.
