Isaac Newton could calculate the motion of the stars. He still lost $4 million following the crowd.
If one of the cleverest people who ever lived could be talked into a terrible decision by a bad argument, our kids don't stand a chance - unless we teach them to see it coming. This is where The Critical Thinking Unit begins: the six best fallacies to start with, drawn from across the unit's core stages. Each teaches one fallacy through the true historical disaster it caused, an original comic, and hands-on activities - and completing the collection later finishes the full unit.
⭐⭐⭐⭐⭐ Rated 5.0 on Etsy & TPT · Six for the price of five - $119.70 value for $99 · Written by a real history teacher, drawn by hand, no AI.
The six stories inside
Most fallacy resources are a definition on a slide and a matching exercise. These teach through storytelling. Your learners don't just find out what a fallacy is - they watch it play out in a real disaster, laugh at it in a comic, then go hunting for it in the wild. That sequence is why it sticks, and why kids come back asking for the next one.
Every pack opens with a true story from history - not a paragraph in a textbook, but a fully illustrated, multi-page narrative. Here are the six your learners receive:
Gambler's Fallacy (It's My Turn to Win): Monte Carlo, 1913. The roulette ball landed on black 26 times in a row, and the crowd lost fortunes betting red had to be next. The odds of that run: about 1 in 127 million.
Bandwagon Effect (Jumping on the Bandwagon): Isaac Newton could chart the heavens, yet he still lost a fortune buying South Sea Company stock, for no better reason than everyone else was.
Slippery Slope (Next Thing You Know): Salem, 1692. One accusation, no evidence, and a town that slid straight down to 19 hangings.
Appeal to Authority (Trust the Experts): Tobacco companies paid physicians to put their name behind cigarettes. "More doctors smoke Camels" sold the world a deadly lie.
Hasty Generalisation (Jumping to Conclusions): In 1917 the Bolsheviks branded anyone who owned a cow or a few tools a "kulak", a class enemy. One detail, one sweeping conclusion, and a nation turned on its own people.
Straw Man Argument (Twisting My Words): How the pacifist philosopher Bertrand Russell had his real argument bent into something easier to condemn, and what it cost him.
What's in every pack (20 pages)
Illustrated historical story - the true disaster, told across multiple illustrated pages.
Original comic - Duchess and Bruno walk straight into the fallacy in a scene your learners will recognise instantly, followed by a "Break It Down" page that connects the joke to the concept.
Real-life examples - spot the fallacy in advertising, social media, news and politics.
Plain-language breakdown - a clear definition and worked examples that build to mastery.
Interactive activities - puzzles, matching, word hunts and a Draw Your Own Comic page.
Hidden Gizmo hunt - six sneaky Gizmos hidden in every pack.
Answer sheet - for teachers, parents and group leaders. No prep required.
You'll receive the six printed A4 booklets listed above (20 pages each), colour and black-and-white pages, with a full answer sheet for every pack. Printed and shipped from the Gold Coast.

My kids absolutely adore the characters and story! It reminds us of horrible histories. I haven't found anything like this pack before and it's easy to print. It's perfect for extension work and discussion. We spend a fair bit of time having a conversation about the examples from history. I will definitely get some more!
