The focus of this activity is for students to have a tactile experience to help build on their understanding of average. Average makes all the streamers the same length, but is anyone in the class in fact of average height?

##### Purpose
• Identify the qualities of a good mathematician
• Demonstrate the qualities of a good mathematician
• Explain and record thinking using a systematic approach
• Recognise and explain ways to measure data, including mean, median and mode
• Use materials and tools to help measure heights
• Compare measurements and make statements about the data
• Understand that a measurement, such as average, may not represent the height of any individual

##### STAGE 3
• Investigate combinations of translations, reflections and rotations, with and without the use of digital technologies (ACMMG142)

##### At the end of this lesson students should be able to answer the following questions
• What are the different ways we measure data?
• When are these different measures used?
• What is the mean, median and mode?
• How do we calculate the range?
• How are the different measures calculated?
• What tools can help us to calculate the mean?
• How can we interpret the data?
• How does this information help us?
• What are outliers?
