it's interesting that mental self-editing can be considered a "weak point." it sounds like he's really doing 2 (fabulous) things at once there - he's clearly on-task, brainstorming his ideas, and then on top of that, he's honing/selecting the ideas to produce quality work. frankly, that is a much more advanced process than simply writing down the first thing that comes to mind. so regardless of any other possible issues... i think major congratulations are in order! (at least from me!)
True. And when I asked my child, he said the same thing too -- not in as much words, but he said he would rather think and write, rather than write something like "I went to the park. I played. I had fun" (which seems to be the sort of writing expected at K level). I am very confused, because my son is able to verbalize why he is doing what he is doing. Yet, I understand that any teacher or tester does not have unlimited time, and just want to get the job/task done.
It is totally normal and typical for an intelligent child to find maths and reading easy, and still struggle with writing, and it is certainly not an indication of any kind of "condition".
It is not that he dislikes writing, just that he thinks and writes, and takes a long time.
I would DEFINITELY meet with the principal! Express concerns and thoughts, suggest what you would like to see, and find out what can be done.
I will try this. Thanks again, everyone. I just worry, because I am not sure what the norm is, and this is a child who did not start coloring in the lines till age 4.5 (which was a super big deal at preschool). If there are issues with writing, I would much rather know now, than later.
