The focus of this activity is to encourage students to use pattern blocks to make a shape and check to ensure or 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.

##### Purpose
• Identify the qualities of a good mathematician
• 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)
##### 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?
