Design a Unit Scope and Sequence

    Help me plan a unit — the sequence of lessons, not one lesson.

Unit topic / big idea: {{unit_topic}}
Grade level and subject: {{grade_and_subject}}
How long the unit runs (number of lessons or weeks): {{unit_length}}
Standards or goals the unit must cover (paste them): {{standards_or_goals}}
What comes before and after this unit, if it matters: {{context}}

Please give me:
- The **essential questions or enduring understandings** the unit is built around.
- A **lesson-by-lesson sequence** — each lesson's focus and how it builds on the last, moving from foundational to more complex.
- Where the **formative checks** and the **summative assessment** fall, and what the assessment should measure.
- The likely **misconceptions or hard spots** across the unit and where to address them.

Sequence it so each lesson earns its place and the difficulty ramps sensibly for the grade level. Align to the standards I gave you; don't fabricate standard codes or add coverage I didn't ask for. This is a scaffold for me to flesh out and adjust to my students. If the unit length or standards are unclear, ask.
