DS is 10. He's left handed and his writing ranges from neat when he really takes his time to very messy. He can't write on the line, his writnig ranges all over the place. Caps are the same size as lower-case letters or he forgets them. The tails on ys and gs are tiny, but rs and ss are really big. He forms a lot of his letters wrongly - from the bottom up.
It's all over the place. I've tried to help him over the years and he can write ok if he's really concentrating on it, but if he also has to think about SPaG and content, he loses the plot. He also can't spot errors in his own work. Can anyone recommend any resources to help him? Thank you!
