This modern animation and discussion of the ancient secrets of Pascal's triangle manages to be topical, engaging, and mathematically deep all at the same time. A great introduction to the power of number theory across multiple math disciplines, woven together with lively storytelling and commentary. This would make a great brain break in an upper-level class or a good introduction to and discussion starter about the topic.

Instructional Ideas

• Assign research projects on the ancient uses and interpretations of the triangle before Pascal
• Use as part of a mathematical history unit where the role of mathematicians in historical context is investigated through the ages
• Create a mind map or word-wall style posting listing the uses and applications of Pascal's triangle (with examples)
• Assign articles and activities from the Dig Deeper section for small groups to investigate and report findings back to the class 

Classroom Considerations

• Viewing video and attached resources requires Internet access
• Speed of narration and high-level language used might require additional ESL supports, perhaps through multiple viewings

Pros

• Funny and quick moving animation
• Math theory interwoven with application and humor
• Broad but accurate coverage of interrelated topics
• Interactive quizzes and discussions
• Multiple deeper investigation resource links provided

Cons

• None
