I would agree generally with Portia. With our homeschooled child with dyslexic/dysgraphic tendencies, I push only far enough to get the weaknesses to within normal limits for age, and accommodate them for all other subjects, to allow strength areas to be free-running.
And on telling time: more than one of our children has had an odd little relative weakness in telling time, in the context of otherwise advanced math skills, at around that age. In our family, I usually just blame this on parents with dilatory habits...
