This cd is a must for any primary school teacher. I bought it years ago when I heard 'House at the top of the tree' on the radio ( by Jonathon Ross if memory serves)on the way to school and thought 'WOW! Must get that for may class!' I have played it to every class I've had since and they all just love it. I was really pleased to find the interactive graphics and words displayed- I always get a volunteer to come to the front of the class and click on the screen. I'm buying another copy for my nephew who's also a primary school teacher.
