We used a good bit of our class today to do self-assessment and goal setting for the 2nd semester trade as well as the next ASPIRE Interim test on February 27. If you were absent, get info and form from Ms. Bogart at the beginning of your next Geometry class.
Our goal for the second block was to reach an understanding of the 4 rules on the investigation from p 367 and keep that information in your in-class section. We also should have come away from class with the ability to perform translations and reflections in the coordinate plane using algebraic representation, a verbal explanation, and a visual interpretation (EX: Reflect N(-1,-3) across the x-axis to get N'. Graph N and notice that it is 3 below x-axis, so N' must be three above; graph it.)
Our other goal was to understand that sometimes a figure can undergo more than one transformation (#4 on warm-up), and SOMETIMES that composition of transformations can be written as one transformation (example on p 373).
A 4 pt grade was taken on HW #1 (the investigation at the top of p 367 is part of that 4 points). We went over all of this and improved the investigation to be usable notes (answering blanks in gold box).
HW #2: pp 370-371:1-3,5,7-8, p 365:17-19.
You need graph paper for p 370. A link to printable graph paper is below.
Also the in-class worksheet over translation/reflection is downloadable below.
