The Geometry math curriculum was designed to be implemented over the course of a single school year. It includes eight units of study over 147 instructional days (including days for lessons, flex days, and unit assessments). We intentionally did not account for all 180 instructional days in order for teachers to fit in additional review or extension, teacher-created assessments, and school-based events.

Each unit includes a specific number of lessons, a day for assessment, and a recommended number of flex days (see the table below) which can be used at the teacher’s discretion.

Each lesson was designed to be implemented within, approximately, a 60-minute class period. A suggested breakdown of a typical class period is shown below; however, this time allotment will vary depending on the lesson and lesson structure chosen by the teacher.

- 5–10 minutes: Warm up
- 25–30 minutes: Anchor Problems
- 15–20 minutes: Problem Set
- 5–10 minutes: Target Task
