Have you been reading to him? Library books and garage sale, second hand store are good ways not to spend alot of money. Has he been in preschool? Also, my son has V-smile game, hooks to the TV just like a regular vidio game, (he thinks its just a game). It has many games (little cartidges) for learning letters, number, colors, groupings. Just pick one of the tv character he likes, we have cars and wiggles. They don't expect him to know all of letters or alot of words, going into kindergarten, just by the end of the year. Alot of kids this age get b,d,p,q mixed up to some degree. They also might get numbers and letter mixed up (5,S). Don't expect him to be smartest in the class, just tell him to do the best he can. Read at least a few times a week and let him play a game like this. One more thing, I was told my oldest son, now 12, wasn't "listening" in kidergarten and first grade but by 3rd grade his teacher had him tested for being "gifted". He is now above grade level for math, and reading, but he has a hard time with creative,essay writing. So, don't stress out so much, if there is really a problem talk to the teacher.
