I’m not an expert but my dd’s handwriting was dreadful and her spelling worse at this age. Last to get her pen licence in her class (after SATS in y6!).My dd is More Able (all SATS scores ultimately above 116 with several perfect scores in “mocks”) and she is NT but found the noisy disruptive classroom setting awful for her, she daydreamed from boredom waiting for the class to catch up.
Every single parents evening the comment was “her spelling and handwriting really lets her down”.
so how did that come about? My fault.
i didn’t realise school did nothing to support these skills beyond the basics - at start of ks2 her teacher gave her 10 spellings extra homework a week to try and help recover and only then I realised FAR too late that learning spelling and handwriting was MY job not theirs. School will likely expect you to be doing the hard work at home, so ask the teacher what to do. You might have to push your dd a bit!
I found spelling games online are good fun. Also try spelling tins where words are on chopped up bits of paper with each word written twice - once wrong and once right eg “said” and “sed” and dc has to sort them into right and wrong piles. Analyse her written work - ask to look at her schoolbooks - and make a list of words that are frequently wrong and target those. Learning words at home for school tests - yes they will be forgotten. So you need to be testing them over and over at home, every single morning at breakfast in writing, aloud on the school run, with a bath-crayon on the tiles at nighttime - whatever works.
you keep as spelling book and build a list of words dc gets wrong a lot, or has been asked to learn in past weeks so you can focus on problem words and recap to secure past victories.
it doesn’t need to be military but if it is routine and regular it will work. Only mark it as a score if dc finds its motivating. Always show them the correction in handwriting yourself not just spelled aloud and ask them to write out the word spelled correctly two or three times. It’s about repetition to internalise the spellings and visualise it on the page with an instinct for “that looks right”.
is your photo of school work? Get her a book with ruled paper, ideally with a faded line midway so she can aim for the right length of tops and bottoms of letters. So hard to write nicely on blank paper.
And more practice for pencil control helps - wipe clean books where you write over the letters, or join-the-dots, practice silly things like “can you draw a perfect circle” (you and dp try with her too - virtually impossible!), can she draw a wiggly/zigzag/box evenly.
Talk to school about how they teach spelling. They might not be teaching what you expect. Teaching phonics is a pain when it comes to spelling because very little useful spelling is actually driven by phonics - I remember my daughter scrawling “sosij” once and the teacher didn’t correct it. Teachers don’t IME point out wrong spelling at this age, unless it is on the list of core words for KS age-related target. Teachers have very little time to mark, and can appear v inconsistent marking wrong spellings. They might say “oh the point of this work was to be creative” and so doesn’t matter. So the message has to come from you: spelling DOES matter,
in the end I realised this “one size fits all”, “they’ll figure it out eventually” approach didn’t work at all for my dd.
when your dc gets older, take spelling really seriously at home. Learn spellings together every week and test at home. I started way too late, and had to drill dd daily to drum correct spellings into her. She hated it.
you can do loads to help before you get to the dire situation we were in!
