Unit 3:  Shapes and Angles

Time Frame:  5  Weeks

 

 

Math > Grade 5 > Unit 3

 

Unit Description

Picturing Polygons is the second unit that addresses constructing, applying, discussing, and evaluating mathematical definitions of polygons.  Students will also investigate various properties of circles, triangles, quadrilaterals, and regular polygons, asking which properties remain constant and which change when larger and smaller shapes are made.

 

Enduring Understandings

·         Meaningful change in our environment can be made if we understand how things are structured.

·         Mathematical words and symbols help me understand the exact nature of shapes and forms.

·         Models assist me in thinking about how to solve problems.

 

Essential Questions

·         Why is it important to observe how things are put together and how they relate to one another?

·         Why is it necessary to use precise language and symbols in geometry?

·         Why do we have models?

·         How can data be used to help me make a model?

GLEs: 8, 11, 15, 17, 18, 19, 21, 22, 24, 25, 26, 27
