Concept-Based Connections

Essential Understandings

  • 2-dimensional figures can be classified into categories based on their properties / attributes.
  • An ordered pair of numbers defines a specific point on a plane.

 

Factual Guiding Questions

  • How does changing the ordered pairs of a set of points transform a figure?
  • What does the first number in the set of an ordered pair tell you? The second number?
  • What are attributes of different polygons? How are these attributes helpful in classifying polygons?
  • What is the x-axis? Y-axis?
  • What does it mean to translate a shape? Rotate a shape? Create a reflection?
  • How do the relationships between sides and angles change in different polygons?

 

Conceptual Guiding Questions

  • Why is it helpful to classify 2-dimensional figures based on their properties?
  • How would you use angles, angle measures, and properties of polygons to solve real-life problems?

 

Engaging/Debatable Guiding Questions

  • Can 2-dimensional figures ever be classified into more than one category?
  • Can multiple 2-dimensional figures be created given a set of defining attributes?
