Just an update. Thanks so much for all the replies and advice.
We’ll be working on strengthening his reading and reading fluency and his general knowledge (A PIAT was done and revealed this weakness). I heard this is a typical thing for a child with ADD (inattentive). General knowledge is picked up incidentally so if a child is busy with internal adventures (wool-gathering), then they will be missing things like the fact that the animal from whom we get wool from is a sheep.
So I guess it would it be day-dreaming instead of wool-gathering? Either way, will we have a summer filled with fun mixed with a little learning. 
Thanks again,
M
