Up and Down (2 Revised edition)

This is book 14 in the A Extra Series. It introduces the word 'go'. This means that the three words 'no, go, to' have all been introduced as 'special' words.

The word 'go' has been used in the phrases 'go up' and 'go down'.

This means that 'down' has also been introduced as a special word to be learnt by sight also. Later, in the English Vowels Series, other words with this digraph are introduced, e.g. 'cow, owl, brown' when the phoneme for 'ow' is formally taught.
