Writing is a much later skill than reading so as everyone has said really nothing to worry about. ORT books aren't the best to encourage spelling skills as they rely alot on "look and say" rather than using phonics.

Learning how to ?sound-talk?
The teacher shows children how to do this ? c-a-t = cat. The sounds (phonemes) are spoken aloud, in order, all through the word. This is called blending ? it is a vital skill for reading.
They will also learn to do it the other way around ? cat = c-a-t. The whole word is spoken aloud, and then broken up into its sounds (phonemes) in order, all through the word. This is called segmenting ? it is a vital skill for spelling
Making little words together
Make little words together, e.g. it, up, am, and, top, dig, run, met, pick.
As you select the letters, say them aloud: ?a-m ? am?, ?m-e-t ? met?. This is blending which is vital for reading.
Breaking words up
Now do it the other way around ? read the word, break the word up and move the letters away, saying ? met ? m-e-t. This is segmenting which is vital for spelling.
Don?t forget the writing box!
Spelling is harder than reading words ? praise, don?t criticise. Little white boards and pens, and magic boards are fun to try out spellings and practising their handwriting
