Throughout Unit 5, students select and use formal
language to describe their reasoning as they identify,
compare, and classify lines, shapes and solids. Students
will also connect transformations to congruence and
symmetry.
Problem Solving, language and communication, connections
within and outside mathematics, and formal and informal
reasoning underlie this unit. Students use these
processes together with technology and manipulative
materials to develop conceptual understanding and solve
problems as they do mathematics. The focus strategies
for this unit are Eliminate Possibilities and Use
Logical Reasoning.
Critical Questions:
- How might you use transformations to verify that
two shapes are congruent?
- How do you describe shapes and solids?
