I am a young teacher in my second year of teaching. I have very little training in teaching young learners. Although I bought this book just a month ago, I have been using activities from a friend's copy for almost a year.
Firstly, it should be noted that this book is 90% pre planned, ready to use activities. It is not a general introduction to the theory of teaching young learners and contains very little on the issue. It does, however, provide activities which have a full plan of how to use them, level guide and photocopiable handouts. Some activities do need preparation from the teacher, but this is all clearly descibed too.
The main strength of this book is the variety of activities it uses. It includes story telling activities, logical puzzles, arts and crafts and even ways of teaching using videos. All of the activities and lesson plans are bang on and I felt they neeeded very little adjustment (if any) before using them in my classes. Using plans from this book, I have made 'instruction machines' with my 8 year olds, exploited a five minute clip of wallace and gromit with my 6 year olds and even have had them make puppets. The language aims of each lesson are clear these activities have made a great break from our textbook on a number of occasions. Some of the activities are shorter, but many are about 20-40 minute activities so take a good proportion of the lesson. I feel this book has helped me appreciate the value of using activities and techniques beyond the simple textbook/workbook exercises that I had become used to. All of my children appreciate this switch too, and have come to look forward to the times when I walk in to the class and say 'right - now put your textbooks under your desk: you won't be needing them today!'.
The only disadvantage is that occasionally some of the activities, especially the craft activties, do assume that the school/teacher/children all have a reasonable stationary collection (like compasses, rulers, glue, colouring pencils, scissors) which unfortunately isn't always the case. I ended up buying scissors and rulers for my classes but they still don't have all of the materials for all of the activities.
I would highly reccomend this book to teachers who are looking for fun and interesting activities which are ready to use.
