DS10 is refusing to do his homework. Usually after a day of no screens, he caves around 5pm to get to watch something before supper. He's still holding out 
He has a diagnosis of dyspraxia (and prob ADHD, ASD) I suspect dyscalculia too and will be assessed this year.
His homework is to:
Write down which numbers between 50 and 80.
Between 71 and 94.
The three largest numbers.
The three smallest numbers.
Write the numbers in the correct order on the number line.
I am stumped as to why he is so stubbornly refusing. Is is something to do with his dyspraxia and ordering? He says it's boring and he hates maths. He can count reliably to 100, knows what bigger/smaller means, has a 100- square in the table...
But why is he still refusing to do it?
