Can you do a lesson for the whole class when they are on different reading levels? Which teacher guide should I choose?

You can group your students based on the reading level(s) within your classroom or across multiple classrooms. This means teachers are able to deliver instruction for these groups separately. When students are grouped based on their reading levels, you will be able to conduct the lesson by introducing the strategies as these occur across all levels. You can model your lessons using the teaching guides from the lowest to the highest level.
