One that's not mentioned: my child's dysgraphia is mild and he is only in RTI wi out an IEP. But, he also did lots of letter flipping and mirror writing as well as words climbing up and down pages and floating away from the red line. Something that really helped him was "letter reflex". He is cross dominant (left eyed, right handed) and letter reflex is a game which helps them become physically cognizant of which direction a letter points to. Hope this makes sense and is helpful.
