Mr. Ammentorp: Integrated Math 2 Digital Agenda
Week of August 31, 2015
Check In/Do Now: M/T: Congruent Triangles- Know, Want to know, Learned KWL Do Now (M.P. # 2) W: Matching isometric transformations and their
coordinate rules (M.P. # 2) Th/F: 1. Find this week’s digital agenda. 2. Read the jobs PowerPoint for today’s collaborative station; Collaborative Group Roles 3.
Choose 2 jobs you would be interested in signing up for and be able to explain each job’s responsibilities in your own words. 4. Take out last night’s homework
and switch it with a partner.
Essential Question (s):
 What misconceptions do I still have about congruence and how can I use appropriate tools to clarify my understanding of the concept? DOK 3
 How can I use the definition of rigid motion to prove two figures are congruent? DOK 3
 How can I use isometric transformations to prove the triangle congruence criteria; SSS, SAS, and ASA? DOK 3
Standard(s) from Instructional Guide:
G-CO—Congruence:
G.CO.A Experiment with transformations in the plane.
2. Represent transformations in the plane using, eg., Transparencies and geometry software; 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 (eg., translation
versus horizontal stretch).
G.CO.B Understand congruence in terms of rigid motions
7. Use the definition of congruence in terms of rigid motions to show that triangles are congruent if and only if corresponding pairs of sides are
corresponding pairs of angles are congruent.
8. Explain how the criteria for triangle congruence (ASA, SAS and SSS) follow from the definition of congruence in terms of rigid motions.

Student Objective (s):
 M/T: By the end of the period students will have worked together to complete and volunteer to respond to at least one of all 9 challenges on
congruence from the PowerPoint activity.
 W: By the end of the period students will be able to correctly identify 5 pairs of congruent triangles using the Triangle Congruence criteria.
 Th/F: By the end of the independent station students will have correctly answered 8 problems on isometric transformations on LearnAlberta
and have completed the accompanying worksheet.
 Th/F: By the end of the direct station students will be able to prove two triangles are congruent using a two-column proof and a triangle
congruence criterion.
 Th/F: By the end of the collaborative station students will have worked together to produce a sequence of transformations that map
manipulatives representing furniture to specific points on a grid.
