MYP maths unit on inequalities and functions for years 4–5 (standard): 5 animated lessons, worksheets and 3 criteria A–D assessments with rubrics.
Students solve linear inequalities, represent inequalities as regions, use function notation with domain and range, transform graphs, and use feasible regions to make decisions with limited resources. The unit is framed by the global context of globalization and sustainability.
What’s included
• 5 animated PowerPoint lessons (65 slides, plus PDF copies): Linear Inequalities; Inequalities and Regions; Functions, Domain and Range; Transformations of Graphs; Inequalities for Decisions
• Each lesson: inquiry question, starter, key ideas, 4 criterion-tagged worked examples, a practice task from levels 1–2 to 7–8 with a model answer, exit ticket and reflection
• 5 worksheets (Word + PDF) in three level bands, with full answers
• Task 1: Criterion A test (50 minutes, 34 marks) with markscheme and marks-to-level conversion
• Task 2: Points in a Triangle investigation (Criteria B and C), counting and proving the number of integer points in a region
• Task 3: The School Fundraiser real-life task (Criteria D and C), using linear programming to plan a bake sale
• Teacher guide: unit planner (key and related concepts, statement of inquiry, inquiry questions), lesson plans, misconceptions and grade boundaries
Why teachers use it
Each click reveals the next line of working, so students predict before you show them. Tasks come with student rubrics, checklists, model solutions and moderation notes, and everything is editable.
