No warm up; went over coordinate reflection hw and assessment review; took assessment, then continued coordinate reflection packet work.
Homework: Watch and take notes on this video: direct link
(Mr M was out on Wednesday). Warm up dealt with topics from the video including rotation order and reflecting a shape onto itself. Passed back Monday's tests. Did a quick example describing a sequence of transformations to carry one shape onto another to check for congruence (which involves writing specifically what steps are needed). Then went to the computer lab and played "Polygraph" dealing with reflections and translations and explored symmetry with symmetry artist.
Homework
nothing new
prepare for reassessments by studying old tests/example videos/notes/doing any missing hw
Warm up on showing if linear equations are parallel or perpendicular and using the distance formula. Got new seats, then looked at several images and played a "which one doesn't belong" game with each set. Then worked out a linear equation model for answering the question "how much does a 100x100 burger cost?" Closed with passing out the practice assessment and going over some of the more challenging problems on it.
