I just posted this on Help-Line yesterday.
I've been training cause-effect as a stepping stone to inferencing. Your kid seems like he may have this part down. I work with Middle schoolers and Highschoolers, but this may be a good for your kiddo since he's doing well with it so far.
I use cartoons to build inferencing skills. They can visually look for the clues that lead to making an inference before trying to find clues inside a wall of text. Make them point out the clues that helped them figure out what happened.
I also recomend to parents to read the funny pages with their kids and explain cartoons that they don't understand. There are also tons of cartoons online. My favorites are Dogs of C-Kennel, Hagar the Horrible, Broomhilda, and B.C.
What happened after the white dog (Kenny) insulted the big dog? >>> The big dog punched him.
- There was a big WHUMP "sound"
- The white dog has a bent nose
Where are the fleas? >>> on Kenny's fur
- The fleas are standing on white spiky tings
- Kenny is white
- Fur might look like that if you were really small.
Who really called the big dog a doofus? >>> The fleas
- The fleas have a megaphone
- Kenny looks very confused in the first frame and his mouth isn't open to talk.
