Salam!
The teacher should always be very careful, have a negative eye and develop the pupils' negative eye too. The Algerian book has always been a failure since it has never been mistake-free.
As for illustrations, the four books are not attractive at all. The choice of colours and pictures is of great importance, especially for young learners.
Concerning punctuation, I really want to know which one is correct in the two mentioned examples, the comma or the semi-colon.
I'm hungry.... I want some....
I think that the semi-colon would be more suitable here.
Of course, the mistakes aren't made on purpose, but they are rather the result of indifference!!!
In the end thanks a million for your valuable analysis.
