MYP criterion B and D tasks

Every task is our own. The help on the student sheet reduces from MYP 1 (a table to fill in and sentence starters) to MYP 4-5 (an open task; extended asks for a proof). Every pattern rule was checked against a brute-force count for many cases, and every number in the exemplars was checked.

The level descriptions say what the evidence looks like in this particular task, in our own words. They are not the IB's criteria; the official criteria are in the IB's MYP mathematics subject brief (PDF). The data in the real-life tasks are made up for each task unless a source is named; each task suggests real data your class can collect or look up.
