With Zearn Math, students learn content in two ways: Independent Digital Lessons and Small Group Lessons. When designing our curriculum and testing it with thousands of teachers and students around the country, we learned that some lessons are better suited for Small Group Instruction than they are for Independent Digital Lessons. It might be that the lesson is an additional lesson on a topic we already have a Digital Lesson on - so teachers may choose to use it for a student needing review. It might be on a topic above grade level, so you may use it for a student with very few alerts and showing strong mastery on paper Exit Tickets. All Omitted Digital Lessons are noted for teachers on each Mission overview page.
