Some of the words that young children can find most difficult are what are known as "sight words" - those which can't be broken down phonetically. Reading, writing and practicing these words as often as possible is a great way to help kids learn the words, and excellent practice in learning how to spell them. I'm putting together some practice booklets to help Small learn his sight words.
Starting right at the beginning, with kindergarten level words, we have "a".

Have fun! Until next time. x
