Math - 2018-19

3.13 - Congruence

The student will 

  • identify and describe congruent and noncongruent figures.  

Adopted: 2016

BIG IDEAS

  • So that I can understand that some shapes are the same even when their position or location changes
  • So that I can create a matching copy of a shape or image




UNDERSTANDING THE STANDARD

  • Congruent figures have the same size and shape. Noncongruent figures do not have exactly the same size and shape.  Opportunities for exploring figures that are congruent and/or noncongruent can best be accomplished by using physical models. 
  • Congruent plane figures remain congruent even if they are in different spatial orientations.
  • Figures that are congruent or noncongruent may be identified by using direct comparisons and/or tracing procedures.

ESSENTIALS

The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to

  • Identify examples of congruent and noncongruent figures. 
  • Determine and explain why plane figures are congruent or noncongruent.
