IB Maths AA SL Sequences and Series Unit

A complete, ready-to-teach unit for IB Mathematics: Analysis and Approaches SL, Chapter 1: Sequences and Series. One editable PowerPoint covers all six lessons, plus a practice booklet, answer key, 60-mark unit test with markscheme and a scheme of work.

Written by an experienced IB Maths lead teacher and former exam marker. The unit follows the section order of the Oxford AA SL course book (2019), so it slots straight into your scheme, but every question is original.

What’s included

• Chapter deck (130 slides, PowerPoint): a clickable contents page jumps to each lesson, with a “back to contents” button on every lesson title slide
• Practice booklet (PDF): one section per lesson, with space to work
• Full answer key (PDF)
• End-of-unit test (PDF): 60 marks, Section A no calculator (Paper 1 style) and Section B GDC (Paper 2 style)
• Test markscheme (PDF) with IB-style M, A and R marks
• Scheme of work (Word): objectives, IB syllabus links, Do Now, worked examples, Exit Ticket and GDC focus for every lesson

Lessons

1. 1.1 Number patterns and sigma notation
2. 1.2 Arithmetic and geometric sequences
3. 1.3 Arithmetic and geometric series (including sum to infinity)
4. 1.4 Applications: simple and compound interest, growth and depreciation
5. 1.5 The binomial theorem
6. 1.6 Proofs

Every lesson follows the same structure

• Do Now: four retrieval questions plus an extension, with handwritten solutions
• Teach-in slides with colour-coded diagrams and steps that appear one click at a time
• Worked examples: the question on one side, the solution building line by line on the other
• Lesson plenary with a “spot the mistake” question and an answers slide
• Exit Ticket: an IB exam-style question with marks, followed by the markscheme so students can self-mark

All maths is properly typeset with stacked fractions, and every answer has been checked. The essential question and IB syllabus reference sit at the top of every slide.

Covers IB AA SL syllabus 1.2, 1.3, 1.4, 1.6, 1.8 and 1.9.

Fonts: the deck uses three free Google Fonts (Baloo 2, Lora and Nothing You Could Do). Install them for the intended look; the slides still work without them.
