Encouraging your child to read, write, or practice other skills is commendable. Ask your son to write a letter to someone (a friend or relative). Watch his process when he writes. Does he have difficulty with writing: a) finding the right words, b) the fine motor skills required for writing, or c) corrections. Your son may see this as more work and less fun. Try to find a way to make this fun! He may use the computer or iPad to improve his writing skills. There are numerous apps or programs that support writing skills that are age-appropriate.
