The real problem this unit answers, framed around Columbus, Georgia.
Workbook handed out, unit tab set, self-assessment scale reviewed.
8–10 items on prerequisite skills. Not graded. Drives the first week's grouping.
One approachable problem from the new standard, no instruction yet.
One problem on the day's standard. Collected at the door and sorted into got it / almost / not yet before the next period.
- · Open with the unit question before the vocabulary. Students should be able to say why "project launch: scale and the site plan" matters before they see a single term.
- · Read the pre-assessment directions aloud and say plainly that it is not graded. Students who believe it counts will guess instead of leaving blanks, and blanks are the useful signal.
- · Score the pre-assessment before tomorrow. It sets the reteach table for the whole first week.
Students talk about the unit question before they compute anything, set up their workbook tab, and take a short pre-assessment that does not count for a grade.
