Took assessment on parallel and perpendicular slopes on the coordinate plane. Then worked some more on the perpendicular bisector worksheet from last week.
Homework: none :)
finish the perpendicular bisector worksheet if needed; due Thurs/Fri
See previous post for resources
Warm up reviewed algebra skills in preparation for new unit (p. 102 #1-8). Then introduced transformations as assigning numbers and functions to movement in space and saw examples from animation and software like Snapchat filters. Learned about the types of transformations as well as which are rigid and which are non-rigid motions. Learned about arrow notation and applied them to figures' coordinates, translating and dilating them as indicated.
Homework: p. 106 #8-12 (CO-A3a) (1A, 3A and 4A only)

Began day with angle relationship puzzle and warm up, seeing how well you can craft a figure that meets certain criteria. Here is that handout. Then did estimation activity in journals, estimating a person's height and the number of folders in a box. Then reviewed transformations, went over homework and examined reflections on the coordinate plane. (CO-A2a)
Homework: p 109: 2 and 3 p. 119: 20 and 21
(CO-A2a) (1A 3A 4A only)

Friday
Began day with angle relationship puzzle and warm up, seeing how well you can craft a figure that meets certain criteria. Here is that handout. Introduced transformations by looking at central question, dealing with functions and movement. Saw several examples including animated gifs, Xbox Kinect/motion capture, and marching bands moving across the field. Learned about the four types of transformations and how to use arrow notation. Lecture notes posted here.
Homework: p. 106: 8-10 p. 109: 2 and 3 p. 119: 20 and 21
(CO-A2a) (1B and 3B only)
