Bach Revision Key Ring
Looks like paint testers in store, but acts as a quick revision tool, print from home/ school.
BACH: 24 colour strips with info & 4 blank spares in PDF.
Comes in A4 PDF digital format.
I suggest to print, laminate, hole punch and add keyring like photo shown.
I use them for:
-important topic info
These should not be the only resource used while teaching Bach. I use these for quick revision!
