I have successfully taught three children to punctuate and write well. In fact, one will be starting college at sixteen. She edits my writing. However, I used all the same materials with this child to no avail. He continues to put commas where there should be periods. He leaves out commas when they are needed. He just doesn't get it. He doesn't "hear" the end of the sentence. We've used Shurley Grammar, Daily Grams, Winston Grammar, Easy Grammar, Rod and Staff and every little workbook in between. Now I'm just having him write paragraphs, which I correct. His little brother writes perfectly. HELP! Does anyone have this problem? My fourteen year old says that her friends from public school write this way - no periods, just a few commas in long lengthy prose.
How can I help this child? Any ideas?
