good suggestion from Lusi…find a subject that he is interested in and then find games relating to that subject that require him to read.
another thing that we tend to forget is that study time does not necessarily have to be stationary sitting at a desk…kids can learn and accomplish the same results while engaged in physical activity…
I did this for my nephew who couldn’t sit still when he was 6 years old:
Photocopied pages from books that he was supposed to be reading…glued them to bristol boards in three different rooms of the house…he was required to find objects hidden around the house based on the clues provided in those pages…(I had highlighted words from those pages to make my own sentences that gave clues about where treasures were hidden.)
He loved the whole process…and I got him to read at least three full pages of text each time.
