Not primary education exactly, but this seems the nearest fit.
DD is 3y8m. She's finished all of Teach your Monster (and seems to understand it all well - she reads things out and about all the time, reads quite complex words/sentences well, and understands/can talk about what she's reading). She's reading Songbirds with me and is up to what they call Stage 4 on that. (She's also doing the equivalent with DH in Russian - we're really delighted with how she's taken to reading.)
Where next? Is there another app to go onto that anyone would recommend / something else to keep her motivated?
I know, this being Mumsnet, that I'll be told my pre-schooler should be out playing in the mud and building forts - she does that plenty, I'm just looking to fill the 20 minute gap in our day where the monster game was.
If it's relevant she's not due to start school until 2022.
