Concept-Based Connections

Essential Understandings

  • Analyzing the characteristics and properties of shapes leads to generalizations about geometric relationships.
  • Shapes and patterns are all around us.

 

Factual Guiding Questions

  • How do we classify shapes?
  • What is parallel?
  • What geometric figures could you draw using line segments?
  • What are some ways to find out how many lines of symmetry an object has? Why does this work?

 

Conceptual Guiding Questions

  • What are the important attributes of a shape?
  • What are the similarities and differences between different polygons?
  • Where might you see examples of parallel lines outside of school?

 

Engaging/Debatable Guiding Questions

  • How can you put together shapes and take them apart to form other shapes?
  • What shapes can you make using only triangles?
  • Is a square a rectangle? Is a rectangle a square? Why or why not?
  • Why might someone need to know the geometric name of a 3-D shape in the real world?
