The book that we use is from the Oxford publishing company that has a digital support, it was called ACE 3. I noticed with the number 3, its title is "Lift-off". It is prepared for a third grade level of primary school, the truth is that it is a little high compared to other books at this level.
Of course, all instructions, questions ... are in English.
In this unit, the students work: vocabulary of professions is worked, the use of the verb CAN and the possessive using 's.
Personally, I think it would be convenient to have more level options because it is quite limited, especially in listening, but it is also true that the teacher can follow the book by not doing exactly what the book guide tells you. In each unit,there's a worksheet of mixed skills with the same topic.
For my students it is much more rewarding when we play games where they can demonstrate everything they are capable of doing, open activities where every student has a place, from a student with difficulties to an advantage one.
The main problem is not the book, what I have to analyze is the methodology that is offered, avoid the master class, the student has to be the protagonist of his own learning.
