Is the sixth grade of PEP the same as the old edition?
It's different. As of May 16, 2023, the sixth-grade mathematics illustrations in People's Education Edition have all been revised, not only the illustrations have changed, but also the covers of all textbooks have changed, which is different from the old edition. People's Education Edition is published by People's Education Publishing House. This version of the textbook is available from primary school to high school, and most schools are also using it.
