Grade 8: Critical Thinking Year Plan

Numbers, graphs and "free" services all carry hidden choices and interests — a thinker reads the data behind the claim and asks who is moving whom, and at what cost.

By the end of Grade 8

What your learner will be able to do.

  • Judge whether a statistic is being used honestly, spotting selective framing, dodgy averages and missing context.
  • Read a graph critically, catching truncated axes, cherry-picked ranges and misleading scales.
  • Tell correlation from causation and judge whether a sample really supports a claim.
  • Estimate risk and likelihood by evidence rather than fear or vividness.
  • Name the techniques of propaganda and mass persuasion and judge how they move crowds.
  • Evaluate the real cost of a "free" service or a contract, weighing data, privacy and the fine print.

How a week works

The screen is the spark. The thinking happens together.

Each week is one short on-screen lesson (about ten minutes) wrapped in something no screen can do: a real conversation. Every lesson comes with a free session guide for the adult — a time-budgeted plan with discussion prompts, an activity, a “talk about it after” question, and the signs to watch for — with a version for parents at home, homeschooling families, and classrooms.

1. The on-screen spark (~10 min)

A hook, the idea, a quick check with feedback that teaches, and a written reflection.

2. The conversation (~15 min)

The heart of the lesson: the big question, talked through — at the table, on a walk, in class. Ask more than you tell.

3. Real life + the journal

Spot the idea in your own week, then capture the reflection in the Thinking Journal — the year’s proudest record.

The year, term by term

34 weeks across four South African terms.

Every grade follows the same four-term journey — looking and wondering, reasons and evidence, other eyes and hidden persuaders, then doing the right thinking — so families and teachers always know where they are. Lessons unlock one at a time.

Term 1 · 10 weeks

Looking & Wondering

Wake up attention in a world of numbers: what data is, where it comes from, how likelihood works, and how our own minds misjudge risk.

Hold onto this term: A number always came from somewhere and someone — notice the choices behind it before you trust it.

  • Week 1: A World Made of Numbers

    How many of today's claims are really claims about numbers?

Term 2 · 9 weeks

Reasons & Evidence

The Grade 8 core: how statistics lie, graphs that mislead, sampling, and the correlation–causation trap — reading the data behind the claim.

Hold onto this term: A statistic is an argument in disguise — ask how it was made before you let it persuade you.

  • Week 11: How Statistics Can Lie

    Can two true statistics tell opposite stories?

Term 3 · 9 weeks

Other Eyes & Hidden Persuaders

The heavy persuaders: how propaganda moves crowds, how persuasion exploits emotion and group identity — and seeing across deep difference.

Hold onto this term: The bigger the crowd being moved, the more it pays to know exactly how — name the tool and resist it.

Term 4 · 6 weeks

Doing the Right Thinking

Apply the year to real-world ethics: data and privacy, the fine print, environmental justice — then reflect on a year of growth.
