hi, I have 27 kids in my grade 2, with 5 groups of level reading. I feel very confuse to manage my class when teaching reading. My questions is while I work with one group, what will the other do. And I just have 40 minute for reading time. WE are from Viet Nam and we just have one book with 27 copies. The reading material is totally similar. That's the curriculum from our Ministry of Education. The whole country just have one curriculum. I'm highly appreciate your academic advices .
