Learning Jenga treats cumulative knowledge as a tower whose higher blocks depend on the lower ones. Each concept that was never truly understood leaves a hole in the structure. The learner may continue upward for a while, but subtraction, multiplication, fractions, algebra, and calculus become increasingly fragile when earlier blocks are missing. Instead of interpreting the struggle as low ability or pushing through more advanced material, trace the skill backward to its prerequisites. Find the earliest unstable concept, pause, and rebuild it to mastery. Only then continue upward. The model turns frustration into a diagnostic signal and explains why slowing down or moving backward can be the fastest way to make durable forward progress.
Origin
MacKenzie Price used a Jenga tower on Modern Wisdom to explain how missing foundational concepts compound as students move into advanced material.
Core principles
- 01Advanced knowledge depends on stable prerequisite knowledge.
- 02An unmastered concept is a missing block, not a reason to keep moving upward.
- 03Repeated difficulty often signals an earlier gap rather than a lack of ability.
- 04The fastest route forward can be to slow down and rebuild the foundation.
How to run it
- 1
Map the tower
List the skills and concepts that the current challenge depends on. Work backward until you reach foundations the learner should already command.
Pro tip Turn a broad complaint such as 'I cannot do algebra' into a prerequisite chain that can be tested one block at a time.
- 2
Find the first loose block
Check accuracy, speed, and the ability to explain each prerequisite. Locate the earliest concept that is missing or unreliable.
Watch out Do not mistake recognition of an explanation for independent mastery.
- 3
Stop building upward
Pause the advanced lesson instead of adding more information to an unstable structure. Treat the pause as efficient diagnosis, not regression.
Watch out Continuing on schedule can hide the gap while making later recovery more expensive.
- 4
Replace the missing block
Relearn the prerequisite through another explanation, worked examples, and focused practice. Continue until the learner can use it without prompts.
Pro tip Try a different resource when the first explanation does not connect.
- 5
Rebuild and retest
Return to the advanced concept and test whether the repaired foundation now supports it. Repeat the process if another gap appears.
In the wild
Price described reaching advanced math and feeling that she had no idea what she was doing. Learning Jenga reframes that moment: instead of forcing more advanced lessons, trace the struggle through algebra, pre-algebra, fractions, division, and earlier arithmetic until the first weak prerequisite appears, then rebuild from there.
→ The learner addresses the cause of the difficulty rather than repeatedly treating its advanced symptoms.
Common mistakes
Advancing because the calendar says so
Time-based progression moves learners onward even when the prerequisite block is missing, making later subjects progressively harder.
Treating the struggle as low ability
A learner may be capable of the advanced concept once the earlier gap is identified and repaired.
Reviewing everything instead of the weak block
Broad repetition wastes time. Diagnose the earliest unstable prerequisite and focus the repair there.
Is it for you?
Best for
Learners, teachers, and coaches diagnosing why progress has stalled in a cumulative subject or skill.
Not ideal for
Independent topics where later performance does not rely on mastery of earlier concepts.
From the transcript
“if you don't understand a concept, that's like taking a little wood block out of your foundation.”
“the reason is because I didn't really have that strong mastery based foundation of some of the lower level concepts that we needed.”
“often the fastest way forward is to slow down, you know, or go backward and fill holes.”
