Notation Cards for Treble and Bass Clef

I have made the treble clef cards to support teaching notation in KS2 with the bass clef set as an extension for a more able child who is learning piano independently. I have ordered the cards, which include some sharps and flats and ledger lines up to 2 lines above and below the staff, roughly in order of difficulty. I plan to print them on different coloured card so that the notes that can be identified using the common mnemonic (every good boy etc) and "face" are on yellow, the sharps and flats for those notes plus C5, D5 and G6 on green and the rest on orange so that the children will be able to identify and be encouraged to move on to the harder sets.
