Mathematics is the Art of Explanation Paul Lockhart, Mathematician

Thursday, November 3, 11



“If you deny students the opportunity to pose their own problems,



to make their own conjectures...,



to be wrong,



to be creatively frustrated,



to have an inspiration,





and to cobble together their own explanations and proofs, you deny them mathematics itself.” -- Paul Lockhart, Mathematician

Problem: Color this Map How can you extend this problem?

Thursday, November 3, 11

Problem: Color this Map • No mapmaker was ever limited to just 3 or 4 colors of ink!

• Yet, mathematicians studied this for fun for over 100 years!!!

• In 1976, “Four Color Theorem” was finally proven.

• There’s a Map Coloring Algorithm... Thursday, November 3, 11

Why Did We Just Spend 5 Minutes Coloring Maps?

How much fun is this?

WARNING: Overuse may be hazardous to attitude and interest

Thursday, November 3, 11

Would this be more fun?

Can you color this map with just 3 colors? or 4? or 5?

Creating a Mathematical Culture at Home

Thursday, November 3, 11

Cultural Belief #1 Problem solving is challenging and fun

Thursday, November 3, 11

Cultural Belief #2 Failures are opportunities to learn

Thursday, November 3, 11

Cultural Belief #3 Celebrate effort regardless of outcome

Thursday, November 3, 11

Cultural Belief #4 Curiosity is always encouraged

Thursday, November 3, 11

Cultural Belief #5 Better to understand than memorize

Thursday, November 3, 11

Cultural Belief #6 Mental math trumps paper and pencil

Thursday, November 3, 11

Cultivate A New Attitude • Perseverance - “I refuse to give up.” • Confidence - “I can do it.” • Intuition - “I have an idea...” • Curiosity - “I wonder...”

Thursday, November 3, 11

Perseverance Reward effort not natural talent

Thursday, November 3, 11

Confidence Built through incremental successes (Be less helpful)

Thursday, November 3, 11

Intuition Do lots of problems (there’s no shortcut)

Thursday, November 3, 11

Curiosity Extend problems and always ask why
