In Classroom Resources, Measurement and Geometry, Shape

The focus of this activity is to discover what it is that students know about 2D shapes and 3D objects. Often students will be able to name some shapes and identify some properties but sometimes this is only a surface level understanding and may hide common misconceptions.

Purpose
  • Identify and name two-dimensional shapes
  • Identify and describe the properties and features of two-dimensional shapes
  • Recognise and describe polygons
  • Identify and name three-dimensional objects
  • Identify and describe the properties and features of three-dimensional objects
  • Describe the similarities and differences between 2D shapes and 3D objects
  • Classify 2D shapes and 3D objects
  • Use the properties of shapes to justify how shapes are classified
  • Recognise and describe the difference between one, two and three dimensions

 

Curriculum Connections: VICTORIAN CURRICULUM F-10
YEAR 6 – NUMBER & ALGEBRA
  • Construct simple prisms and pyramids (VCMMG228)

 

At the end of this lesson students should be able to answer the following questions
  • What is a 2D shape? What is a 3D object?
  • What are features of shapes? What are properties of shapes?
  • What is the difference between the different dimensions?
  • What are the similarities and differences between 2D shapes and 3D objects?
  • What is a polygon? Are all 2D shapes polygons?
  • What is a regular shape? What is an irregular shape?
  • Can you describe a pyramid? Can you describe a prism?
  • What is the difference between a pyramid and a prism?
