I blogged about the app sentiopiary (now known as grow grammar) a while ago. This quick video explains how it works: Grow Grammar - Create - The Beautiful Apple from eeiioo on Vimeo . Now the app is priced at £4.99 and while it is a great way to revise SPaG, with school budgets tightening it may not be affordable for some. However, I have recently discovered a website that does a very similar thing. FoxType's Sentence Tree is a free website where you can type in a sentence and it will define every part, for example: Having this open on your laptop and checking the odd sentence as a quick reminder for children and can be a really useful revision tool.
