• Authentic context with simplified language to support meaningful reflection on answers and engage information literacy skills

  In this task, students are asked to adapt a hot chocolate recipe using a different “strength” of chocolate bar which affects the quantity of cocoa.

Students should be able to:

• form and simplify ratios
• find percentages of an amount
• find equivalent ratios
• share a quantity into a ratio
• represent ratio/proportion in another (e.g. bar model, table of values, linear graph sketch) if being assessed against criterion C
• interpret their solutions in context
  It is recommended to give students at least 1 hour for this task. A calculator (non-graphical) is allowed depending on the calculation skills of your students.
