Full assessment:

• A six-part structured question to help students reach the aim set
• Authentic context to support meaningful reflection on answers
• Criteria C and D rubrics for MYP4/5
• Strand-aligned task-specific clarifications
• Complete working and solution

In this task, students are asked to find the ideal pricing strategy for an event based on research conducted on a sample of the target population.

Students should be able to:

• find the equation of a line given two points
• understand function notation e.g. f(x)
• move between different forms of quadratic functions (standard form, factorised form and vertex form)
• sketch a quadratic function given its equation

It is recommended to give students 1 hour for this task. Advised is non-calculator or at least a non-graphical calculator so student's function sketching skills can be assessed. Also having students structure their own answers on a separate paper allows criterion C (communication) to be assessed more completely.
