I have recently come across the “Minute of Listening” project. It looks really great
It costs £40 for a single school license. If I was a class based teacher I would definitely be asking my school to invest in it. As well as being simple to use the support materials look great as well.
I recommend taking a look at their website. I’ve downloaded a sound mapping sheet that I plan to use with my pupils. If you are planning to take part in the BBC ten pieces listening project you will find the ideas page invaluable.
