You’ll find a lot of teachers are unaware of dyslexic tendencies, and have very little training. Those I’ve spoken to suggest it’s about letters being backward and can’t read.
Neither are completely true!! When I’ve said are they XYZ? They usually surprised that’s a sign of dyslexics.
The not being focused, the need to cause issues in class, etc - whilst they do do this, there are coping strategies teachers can put into place to keep them on track - and I don’t mean colour paper or reading rulers!
Things like word banks, visual timetables, written instructions on the board or in front of the child, breaks, step by step instruction rather than full on teacher talking without and physical breaks or example - everyone write the date - teach - talking partners, physical or practical example, write learning objective, more teaching - work
Rather than teach
Now
Write the date
Write to learning objective
Write a story
A lot of dyslexics can’t follow 10 instructions at once and will then mess about!! I’ve seen it happen
Have a look and ask what training is given
