Here is another activity that is suitable for reinforcing the position of notes on the piano. Perhaps the pupil could use a finger puppet to jump, hop, crawl and leap to the notes of the word. You could -
jump, hop, crawl and leap to the notes of the word staying in the same register. Here is an opportunity to emphasise high, low and in the middle notes.
jump, hop, crawl and leap to the notes of the word going down or up.
jump, hop, crawl and leap to the notes of the word all over the piano. For example, a high B, a low D or an in the middle G.
jump, hop, crawl and leap to the notes of the word whether they are line or space notes, as specified. If any words contain the letters C, G or F, use this as an opportunity to reinforce signpost notes.
