A complete assessment menu for the MYP Year 11 Extended unit “Sampling, correlation and regression: how much a sample can wobble, and how to measure a line’s fit with numbers”: six original tasks covering all four MYP mathematics criteria, with full mark schemes. 32 pages.

The six tasks:

• A1: Quick check: samples, covariance and r (criterion A, 30 minutes)
• B1: Changing the units: what happens to the line? (criterion B, 50 minutes)
• C1: A note for the stall owner (criterion C, 35 minutes)
• A2: End-of-unit test (criterion A, 50 minutes)
• D1: Fertilizer and the rice harvest (criterion D and C, 50 minutes)
• D2: Counting life on a reef (criterion D and C, 50 minutes)

Part 1 is the photocopiable student sheets, one task per page, each with a task-specific clarification so students know what each level looks like before they start.

Part 2 is the teacher material: when to set each task, the unit’s key concept, related concepts, global context and statement of inquiry, then for every task a question-by-question mark scheme, exemplar answers at different levels, differentiation (a way in for anyone stuck, and stretch), and vocabulary and sentence starters for students learning in English. Parallel versions of the tests are included for when students may already have seen them.

Every task is original, written by a serving Head of Mathematics with thirty years of teaching. The level descriptors themselves are not reproduced: each task has its own clarification describing what levels 1-2 to 7-8 look like in that task, to use alongside your school’s current MYP Mathematics guide. Not produced or endorsed by the IB.

Format: print-ready A4 PDF, not editable. Questions are set as printed text with no answer spaces, so students work on paper.
