Need information for English private classes.
Hi, can anyone introduce me to some English books designed for teaching in private classes? I need to know which of them works the best for kids, juniors, and adults. Because there are tons of instructional materials out there that make it hard to decide. That's why I decided to ask here. Thanks in advance

Question

Answer

I'd chose something that might interest the target audience.  When I learnt French many years ago we had to learn about a family and their shopping, incredibly dull to a 12 year old boy.  So I suggest look at which books sell well in your own language to that age group and try to find the English originals.
