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
Curriculum Connections: NSW SYLLABUS
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?
