Working with money

Mathematics · Mathematical Thinking · meta

Model real-world problems involving measurement, money, and time by choosing appropriate representations and interpreting results in context

What mastery looks like

  • Choose whether to use a bar model, number line, or equation for a measurement problem
  • Model a multi-step money problem with equations and interpret the final answer as change or total cost
  • Create a line plot from measurement data and use it to answer questions about the real-world situation

Check your understanding

When Working with money solves a real-life maths problem — like calculating how much fabric is needed for a project — can they choose the right representation (a diagram, a table, an equation) and explain what the answer means in the real situation?
