I was also doing the Genki Phonics poster course with my nephew. It’s the first time I’ve used it one-on-one with an English speaker and it was so cool to have a surfer-dude five year old rush in each morning saying “can we do more learning please?!”
We probably knocked his reading age up by a good 6 months or so.
He was also wanting to do phonics on the beach (!) so we …
1. Wrote up all the graphemes (letter or letter group) he’d done so far,
2. Shouted out words (sometimes emphasising the phonemes like “sh – ar – k” )
3. Ran to each grapheme in turn.
Warning, don’t try this racing against kids unless you want to get really tired really quickly!
I guess you could also try it in the snow!
