I think the toughest thing for me about these books is trying to pinpoint exactly what the book is trying to teach in each lesson. From my understand, here are the "targets" of the first lesson for each grade:MG1 - Introducing oneself, what one is and likes MG2 - Introductions of self and others, giving and accepting apologies MG3 - "I'm looking forward to..." (future & lengths of time), "I'm interested in..." (expressing how you like things?)Does this make sense to anyone else?
