In no particular order but if they are useful to you feel free to take them. I only taught Wjec for a short time so it is by no means a perfect set of lessons or resources but there may be some items of use to someone just starting out.
Attached are all my resources that I use to teach the rivers topic.
The power point is pretty much the whole topic and there are a number of worksheets to help with cycles and key words.
Suitable for Y9/GCSE
Lessons and resources I have used/created to teach theme 2 of the Wjec spec... not perfect lessons, need differentiation, challenge and assessment opportunities but provides a good skeleton to your planning if you are new to teaching it.
Geography - Y9/GCSE
Supplied is a list of resources and the slides that I have used in the past to teach the topic to my students.
Assessment also supplied
I barely taught this theme and no longer teach it after moving to a different exam board. Here is a selection of slides and resources that you might find useful in producing your own lessons.
