Warm up dealt with the angle of rotation for an octagon. Went over the mechanics/specifics of transformations on the Euclidean plane in detail, describing the similarities and differences among rotations, reflections, and translations and how to accurately describe each.

Homework
work on project (due Nov 6, assigned 10/16): prompt + rubric
Take notes on this video I made: direct link
Warm up was based on the video above, describing a sequence of rigid motions to carry one triangle onto another. Returned briefly to the coordinate plane to rotate a figure around a non-origin point by rotating the paper around and counting using the new center as the 'origin' and then did more practice with describing steps to carry one shape onto another. Passed out practice assessment, some classes had time to work on it before bell rang.

Warm up involved analyzing transformation rules. Went over practice assessment in small groups, then took assessment, then worked on projects (or tessellations if projects done).
