Teaching reading to a 3rd grader?

[lizzie j]

I tutor a third-grade boy in reading once a week. I have no idea how to even really help him, since he gets frustrated within 30 seconds, and can't read sentences like "The mouse ran into the barn." It seemed like he just started making up sentences he thought should come next after the ones I helped him with. I kept trying to help him figure out how to phonetically sound out words, but he wouldn't even try or pay attention. Basically, he can barely read (or can't at all sometimes) what I read in kindergarten.

Does anyone have any ideas that would help him learn how to sound out words, recognize some words (such as "like", "and"), or anything like a little game that would help him and keep him interested?
Thanks!
