My daughter just turned 6 last month - she is in kindergarden in Akron Public Schools in Ohio. They have a program called the 100 book challange here... it asks parents to read w/ their kids 30 min a day. You can read in 2 - 15 min sections or one long section. The first books she started with picture books w/ one word - like a pic of a red ball & a word Ball under it. In December she went to the next level (which they call YY) which are short repeating sentences like... The leaves are red. On the next page it would be... The leaves are green. On each page they would have a picture of a tree w/ the different colored leaves on it. Also, the teacher send home one new word a week to learn as a "sight word" (words they should know by the end of 1st grade without having to sound them out) and I took index cards, wrote the words on them & we try to do the "flash cards" 6 days a week - she currently has about 60 of the 100 words she has to know by the end of 1st grade down. She still has issues with the th, sh & ch sounds because they blend together to make different sounds the normal for her.
With the 100 Book Challange - they require the kids & parents to point to the words as they read them. So, even when I read her regular stores I have been pointing at the words as I read to her & her younger brothers. It does help them to see where you are coming up with the words you are saying.
Here I have picked up a few books at the dollar stores that are easy to read & work w/ her sometimes when the school doesn't send home book. You maybe able to go to a libary and get book or maybe they have a program that is free that will help him.
As for the spanish aspect - I don't know how to help you there - so sorry!!!
