Elementary – distinguishing even and odd numbers: Your session facilitator will have a hard copy of this lesson sequence!
Middle school – scientific notation: Note that this is a lesson, rather than a lesson sequence; but it still demonstrates some of the same pedagogical ideas. It is shorter than the others, so be sure to look at other materials, as well.
Other – basic measurement: This lesson sequence covers elementary-level content, but targeted for students thinking at a collegiate level. Given this, it is unlikely to be directly applicable to your classroom, but gives a good model of how you can return to foundational content that your students lack, but approach it in a way that feels age-appropriate for older students.
