The dinner table can be an ideal place to address carry-over goals. The child gains the spotlight (fun and motivating!), the parents or older siblings can model and/or reinforce good productions and homework doesn't add to the parents’ workload (so it gets done!). I've started sending home “conversation starters” with some of my artic kids, but it would also be great for higher level language or fluency students. The language environment is relatively controlled because it’s shaped by the topic and, because it’s “homework,” the child has that little reminder to focus on their current sound target. You can pick up twenty conversation starters here.
And they’re so entertaining, you might use them in your own home!
