For the review classes: We re-worked problems from the Transformation Unit Test from blank tests in class. All classwork for final review blocks should be written on a piece of paper that can be turned in with review assignments.
We went over the first review assignment and the warm-up. The new assignment was handed out; we then used class time to work on the "Build Your Own Notes" page for points of concurrency (did cheer in class). The Triangle Test was returned and we re-worked problems 10-21 to make sure we understood our mistakes. All tests were collected; none will leave the classroom. The 2nd review is attached, with the textbook part of the review written on the notes pages for constructions.
Answers to review will not be published immediately.
In 1st and 2nd - we did investigation 2 on p 375 - making a strong connection between dilation and the definition of similarity. We wrote up the definition of similar polygons from the bottom of p 374 with sketches about CORN~PEAS from p 377. We wrote up C-57 from p 375 based on investigation: If one polygon is a dilation of another polygon, then the polygons are similar. There was a sketch on the board to copy (get from friend). We then wrote up a second definition for similar figures based on C-57: similar geometric figures are figures for which a sequence of rigid transformations and/or dilations can map one exactly onto the other. (no sketch needed). No need to write up C-58 from p 376 as we wrote it in a previous conjecture: all circles are dilations of each other and similar to each other.
We looked at some dilation questions from the PARCC test and a demonstration of dilation without a grid on Geogebra, and then we completed a Performance Task that required full understanding of dilation without the coordinate grid. (Attached) I then passed out the Final Review study guide and the first assignment. (This is attached two blocks prior.)
