Teacher guide reSolve: Real World Algebra: Exponential Functions

TLF ID M021856

This sequence of two lessons explores exponential functions as seen in the real world, linking the representations of function rules, graphs and tables of values. Students consider real world objects and data that can be described using exponential functions. They use simulations and modelling to investigate transformations, reflections and stretches to graphs of exponential functions and how these are reflected in parameters in the function rules. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources. This sequence is part of the reSolve: Maths by Inquiry special topic 'Bringing the Real World into Algebra'.

Educational details

Educational value
  • This resource is valuable for the year 10 mathematics content descriptions about the connection between algebraic and graphical representations of exponential relationships. Students manipulate visual, tabular and graphical representations to build conceptual links between various representations of exponential functions.
  • The resource is also of value for supporting the Information and Communication Technology general capability as students use simulations and digital models to generate data and information to support their understanding of geometry in everyday contexts.
