Full assessment:

• Questions with subparts to help students reach the aim set
• Authentic context enhanced with diagrams to support meaningful reflection on answers and engage information literacy skills
• Criterion D rubric for MYP2/3
• Strand-aligned task-specific clarifications
• Working and sample solutions
• Spaces for answers so this assessment is print-and-use ready

In this task, students are asked to complete an advert for a small catering business, taking into consideration cooking times, space restrictions, and the aim to maximise profit.

Students should be able to:

• form and solve literal equations/formulae from worded contexts (e.g. s = 10 + 2m, s = 7 + 3m then solve 10 + 2m = 7 + 3m to find a common solution.)
• substitute into formulae/ literal equation (e.g. when m = 6, s = 10 + 2 x 6 = 22)
• 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. This could be developed into also assessing criterion C as well if used within a systems of equations (simultaneous equations) unit where students could also solve by graphing.
