Congruence of Polygons

Strand: Shape and Space (Transformations)
Outcome: 6

Curriculum Focus

This sample targets the following changes in the curriculum:

• The general outcome focuses on describing and analyzing position and motion of objects and shapes; whereas the previous mathematics curriculum focused on applying coordinate geometry and pattern recognition to predict the effects of translations, rotations, reflections and dilatations on 1-D lines and 2-D shapes in the Grade 9 curriculum.
• The specific outcome focuses on the understanding of the congruence of polygons; whereas the previous curriculum focused on the congruence of a triangle in the Grade 9 curriculum.

Congruence of Polygons addresses the following outcomes from the Program of Studies:

Strand: Shape and Space (Transformations)
Specific Outcome:
 6 Demonstrate an understanding of the congruence of polygons.

What is a Planning Guide?

Planning Guides are a tool for teachers to use in designing instruction and assessment that focuses on developing and deepening students' understanding of mathematical concepts. This tool is based on the process outlined in Understanding by Design, by Grant Wiggins and Jay McTighe.
