Any student can be taught to read. The following is geared to Kindergartener's, but will work with any grade, including Special Education.
Using a white board easel and marker, write the number 1 on the far left, and make 10 lower case a's in a straight line. Tell the class to watch carefully. Tell them a is a vowel and makes two sounds, (We are not going to talk about schwa sounds now). Using your marker, make a straight line on the top of 5 random a's. Tell the class when they see this little straight lines the a says it's name. That is called a long vowel sound. Point to all of the a's that have a line above them and tell the class a says a. You go first and say a, and have the class copy. Give them praise. Next, put a curved smile on top of the remaining a's. Tell the class this smile sign makes the letter a have a short vowel sound, as in cat, rat, bat, and hat. Have the class copy you as you point to a short vowel sound and say the correct sound. Be cautious. Short vowel sounds do not end with an a sound. Model the line of a's saying the long or short vowel sounds. Have a few children come up and, using a pointer, say the vowel in a correct way.
Pass out a white half inch binder with a clear plastic on the face, and a copy paper. Also write on the board, My Poetry Notebook. Students are to copy the words along with their name, and decorate the copy paper. After about 20 minutes, pass out a paper with long and short vowels. There should be at least 8 lines and the papers should have long and short vowel sounds and have been three hole-punched. Practice saying the long and short vowel sounds with the class. Have a few lines on your easel, and call a few students up to read the vowel sounds.
The next day go over the a list again. Pass out a tag board square with a long and short vowel sound. Then introduce the vowel e, the long and short e. Basically you will repeat these lessons until you have gone through all the long and short vowels. You are going to use the vowels a, e ,i, o, and u.
W is a vowel when it follows another vowel. Y is a vowel when it is not the first letter of a word. When I was in college we were taught U is a consonant when it follows a Q. I can back up the W and the Y rule, but I can't even google the U rule. Best to leave it out of your instruction.
Ask your librarian for a book on Poetry, or ask a co-worker. Once or twice a week, add a new poem to your student's binders. Always begin with the first poem. Have students point to a room as you say the words. You will be surprised at how quickly student's catch onto the words. Happy Reading!
