Great resource for teachers

This is by far the best grammar app I have come across. A fabulous resource for teachers. The kids in my class love the song. It helps them to remember the rules. The exercises are a fun way to reinforce the rules. Are there any other apps for the rest of the often confusing grammatical rules in our language? I hope so.

great for english!

This has been one of the best ways to teach the apostrophe. So many kids struggle with ownership and this has been a great way to make sure they are getting it right. A hit with both primary and secondary! Keep them coming!

Really nice app

Saw the video on You Tube. Nice idea and very simple. Good song, great music and sounds very professional. Good to hear an education song that takes the music seriously, and isn't just for kids.
