A complete, ready-to-teach IB MYP Criterion B summative assessment on square numbers — designed for MYP Year 2 (Grade 6/7), but easily adaptable for stronger MYP 1 groups or as an extension task lower down the school.

This bundle contains four separate, fully-editable Word documents, so you can hand out exactly what each audience needs without any extra formatting:

Task Sheet — the official MYP cover sheet (unit details, key/related concepts, global context, statement of inquiry, ATL skills, conditions) ready to drop into your unit planner or LMS.

Investigation Exam Paper — a 12-question, step-by-step student paper (38 marks) that scaffolds students from spotting the n² pattern, through a second visual “gnomon” pattern, to predicting and justifying general rules. Includes drawable dot-grids and a worked diagram example, so no extra prep needed.
Mark Scheme — full worked solutions with question-by-question marking notes, strand references, and a suggested (non-official) points-to-achievement-level crosswalk for quick, consistent marking.

Task-Specific Rubric — genuine MYP-style achievement level descriptors (0, 1–2, 3–4, 5–6, 7–8) across all three Criterion B strands, mapped to specific question numbers for fast, defensible grading and easy moderation.

Why teachers like this resource:

Saves hours of rubric-writing and paper-setting time.
Strand-by-strand question mapping makes level-awarding fast and consistent across a department.
A gentler entry point into pattern investigations than typical MYP tasks — ideal for building Criterion B skills before tackling harder topics.
Fully editable — retitle, rebrand with your school logo, or adjust question difficulty in minutes.
