In Classroom Resources, Measurement and Geometry, Shape

The focus of this activity is to encourage students to check their shape to ensure/prove that it is a hexagon. Students need to develop an understanding that good mathematicians find solutions to problems, check to see if their solution is correct and explain their thinking.

  • Identify the qualities of a good mathematician
  • Read numbers written on the board
  • Apply number knowledge to say the correct number, for example, say the number that is one more than the number on the board
  • Identify and name familiar two-dimensional shapes
  • Identify the properties of two-dimensional shapes, including sides and corners
  • Explain and develop a definition for a side or a corner
  • Use shape blocks to create new shapes
  • Check solution by identifying and explaining properties of the shape
  • Explain why a solution is or is not correct


Curriculum Connections


  • Sort, describe and name familiar two-dimensional shapes and three-dimensional objects in the environment (ACMMG009)


  • Sort, describe and name familiar two-dimensional shapes in the environment (ACMMG009)


At the end of this lesson students should be able to answer the following questions
  • What are the shapes in the pattern block set?
  • How can you describe these shapes?
  • What is a side? What is a corner?
  • Can you explain what is a side/corner?
  • What is a hexagon?
  • Can you use these shapes to create hexagons?
  • Can you explain how you know the pattern/shape you have created is a hexagon?
  • Can you explain why this shape is not a hexagon?
