2. Symmetry and Origami
Unit Overview
Symmetry can be found in objects that we use in our daily lives and in nature.
Origami can be used for studying the characteristics of shapes and how they
are made. This will develop their foundational knowledge and will allow
students to appreciate designs, art, and nature. In this unit, students will also
be able to build a foundation for studying solid figures and continue to learn
the properties of all shapes.
