On Sunday, Mathilda played through London Bridge. She then told me she needed to practise the final phrase. I asked her how many times and she said three. This is the first time she's made an independent decision about what needs more work and then volunteered to do it.
The list of pieces now runs as follows: Twinkles in C, B and F#, Cuckoo, Honeybee, Lightly Row, French Children's Song, Mary Had a Little Lamb, London Bridge. This week we learn Aunt Rhody and next week, maybe, Au Clair de la Lune.
The other thing to note is that we've cracked lucky dips--and the secret is granularity. We can't have a card for every single thing, but batches work fine, especially when we're working on concentration an playing more pieces together.
