Q1,W6: September 17-21

TeacherKristin Andreason
Subject AreaGeometry Honors
Grade Level8
Week #Six
Unit of InstructionUnit One: Definitions, Segment and Angle Pair Relationships; Unit Two A: Triangle Congruence and Proofs
Standard(s) Taught

MAFS.912.G-CO.4.12:  Make formal geometric constructions with a variety of tools and methods (compass and straight edge).  This includes copying a segment, copying an angle, bisecting a segment, bisecting an angle, constructing perpendicular lines, and constructing a line parallel to a given line.

MAFS.912.G-CO.1.2:  Represent transformations in the plane, describe transformations as functions that take points in the plane as inputs and give other points as outputs, compare transformations that preserve distance and angle to those that do not.

Learning Targets and Learning Criteria
  • Students will be able to use tools to precisely copy a segment, an angle, a segment bisector, an angle bisector, a line perpendicular to a line, and a line parallel to a line.
  • Students will understand how to draw transformations of reflections, rotations, translations, and dilations.
  • Students will be able to find the coordinates for the image of a figure when a transformation is applied to the pre-image.
  • Students will be able to distinguish between transformations that are rigid and those that are not.
Classroom Activities


  • 5th and 8th period will do a constructions project, creating designs using compasses (2nd period will not do this because of the teacher duty day on Monday)


  • I will introduce Transformations and students will complete Transformations overview worksheet for their ISN (page 11)


  • Students will watch Geometry Nation videos (Section 2, topics 1 and 2) and fill in workbook pages
  • We will then practice graphing a figure and then translating and reflecting it
Assignments Due
  • ISN page 11 must be completed
  • 5th and 8th period will complete the constructions activity
Additional Resources

All IEP and ESOL accommodations will be provided.
