+ Fallacy Detectors + Fallacy Handbook
What's Included
This 48-page printable pack includes materials for 10 lessons plus a cumulative assessment:
- Lesson Plans (23 pages): Detailed lesson plans, each focusing on a different logical fallacy.

- Worksheets (21 pages): Printable worksheets, one for each lesson.

- Cumulative Assessment and Answer Key (4 pages): A 25-point assessment covering all ten fallacies, with an answer key included.

Duration
The materials include ten lessons followed by a cumulative assessment. If you use every component and add the Fallacy Detectors course, each lesson takes about 60–75 minutes.
For shorter classes, you can skip Fallacy Detectors, assign the worksheets for homework, or divide a lesson across more than one class period.
Optional Addition: Fallacy Detectors
Critikid's online course, Fallacy Detectors, teaches the same ten fallacies through an animated, interactive adventure. The course is optional, but works well alongside these lessons.
You can save 20% by purchasing these materials with a pass to Fallacy Detectors in the Logical Fallacies Teachers' Bundle.
For classroom teachers who want multiple passes to Fallacy Detectors so students can work through the course on their own devices, a For Schools subscription is the best option.
Why Choose These Lesson Plans and Worksheets?

As a teacher, I know the value of ready-to-use lesson plans, so I designed these to require minimal planning.

- Consistent Format: I kept things simple by using the same structure for every lesson and worksheet.
