As a side note - I always found the North Lanarkshire review schedule at the beginning of a Stage a bit too fast for the majority of my kids. I hope your school allows you to slow it down (if that is what your class needs).
If you click on each of the pictures below, it will take you to a file containing the games and activities I've made for that phoneme. I've included a page in each file that explains the games/activities that are included in that file. You will find that the main game and activities are largely the same from file to file, so once your class understands an activity, they should be able to work independently on that activity with a new phoneme.
I hope your class enjoys using these and that they save you a little bit of preparation time.
