Now that your Word Wall is set up, you will need to start introducing some sight words along with your CVC (consonant-vowel-consonant) words. This card set by Smethport is a good one with the words printed on colored cards that are easy to read in ball-and-stick font which is used in most public schools today (Denelian font used to be used-otherwise known as fancy font).
I suggest introducing only 2 sight words at a time, then when those are mastered move on to two more. Make sure that you always review the words you have taught before.
*Remember sight words are words you recognize by SIGHT. They are not to be sounded out.
