Lesson summary

As a ‘thought starter’, students watch a short clip about a method of open-sea farming created by Sealeaf. To investigate the real-world application of this innovative farming method, students explore global mean sea levels from 1880 to 2013. Using a graph containing authentic data, your class will consider historic trends, calculate gradients of line segments, and comment on what the gradient represents. Finally, students will hypothesise who will be most affected by future sea level rise.

Learning intentions:

Students will...

  • understand how to read data from a graph
  • will calculate mid-point and gradient and comment on these in context
  • discover the impact of sea level rising on a global scale.

Success criteria:

Students can...

  • describe the key features of the graph.
  • calculate mid-point and comment in context.
  • calculate gradient and explain its context.
  • conduct research for reliable sources of information.

Curriculum Mapping

Australian Curriculum content descriptions:

Year 9 Mathematics:

  • Solve problems involving direct proportion. Explore the relationship between graphs and equations corresponding to simple rate problems (ACMNA208)
  • Find the midpoint and gradient of a line segment (interval) on the Cartesian plane using a range of strategies, including graphing software (ACMNA294)

Syllabus outcomes: MA3‑2WM

General capabilities: Numeracy, ICT Capability, Critical and Creative Thinking

Cross-curriculum prioritySustainability OI.1

Relevant parts of year 9 achievement standards: Students make sense of the position of the mean and median in skewed, symmetric and bi-modal displays to describe and interpret data. Students find the distance between two points on the Cartesian plane and the gradient and midpoint of a line segment.

Time required: 60 min.

Level of teacher scaffolding: Low – teacher may need to demonstrate skills.
