BarbieJellyBabyBrain don't most kids learn to spell 'boy' and then add an 's' to make it plural?
They learn 'oi' first in phase 3 (usually Reception) and then learn 'oy' in phase 5 (usually Year 1, but can be end of Reception). Phase 5 is also when they are taught about the split digraph, although that takes a while to embed. They are also taught about choosing the 'right' sound when they are being taught about alternative spellings for the same sound and that if the 'oy' sound comes at the end of the word, it will be the 'oy' spelling. So then they would know that boy is spelt with 'oy'.
The other thing about 'boy' is that it is a word that the children see a lot all over the place (for example on toilets!
) so they would probably be quicker to learn the correct spelling, like other common words.
This looks like a child who has only been taught phase 3 but the handwriting betrays that level of development. There is something off about the handwriting, that I I can't quite put my finger on! And also they appear to have just bashed out this quite lengthy and complex sentence on a whiteboard, which seems strange as well somehow.
However, even in the unlikely event that the child actually wrote this, it's pretty obvious that it did not come from then, because kids of that age do not give a flying fuck about toilets!
