If you have your own Ukulele at home, you can keep practicing the songs you learnt with Mr Jones don't break ma bones. There are lots of resources on the internet which you can use to remind you of the different chords. Please ask an adult to help you search for them. You can also view the video below from CBBC.
This link to 'Ros plays the ukulele' is great . There are 5 tunes you can learn to play along with. It would be great to see a film of you practicing these new tunes.
