Why "Sets of Related Lessons" and not "units"?
Sets of Related Lessons are designed to have a more targeted focus than a typical "unit". They can be completed in eight to 15 days. The combination and sequence of developing understanding and solidifying understanding tasks provides increasingly complex opportunities for students to make sense of concepts. Students have multiple opportunities to study the concept(s) while being exposed to a broad range of situations and representations, which supports students' flexibility with ideas and aids in the transfer and application of new knowledge to new situations.
The IFL's Sets of Related Lessons include eight high-level tasks designed around key mathematics concept, and accompanying lesson guides. Sets of Related Lessons can be strategically integrated into existing curricula.
A Set of Related Lessons has two types of tasks: developing understanding tasks and solidifying understanding tasks. Tasks are sequenced to provide students with opportunities to investigate concepts and skills in a coherent way. First, to make discoveries and then to form mathematical generalizations related to the concepts under study.
Sets of Related Lessons include:
- an outline of the concepts students will study;
- an articulation of strategies and representations for students to learn and/or use;
- multiple and varied forms of formative assessment, including opportunities for students to write about their mathematical understanding; and
- structures and routines to support students' engagement with tasks, including information about:
- setting up the task so students have an entry point;
- supporting students in exploring the mathematical ideas developed in the task both individually and in small groups; and
- engaging students in teacher-orchestrated discussions to deepen and solidify their understanding of the key mathematical ideas.
A unique aspect of the Sets of Related Lessons is the identification of essential understandings (EUs)—underlying mathematical truths—within the lessons. EUs drive the sequence of the solution paths and the discussion questions outlined in the lesson guides.
The IFL also offers performance-based assessments (PBAs) to assess students' learning of concepts and practices in specific Sets of Related Lessons. See here for more information about the mathematics PBAs.
