Everyone Can Learn Math

Here’s a new video from Jo Boaler at YouCubed.org.

Boaler’s Four Key Research-Based Messages

There is a huge elephant standing in most math classrooms, it is the idea that only some students can do well in math. Students believe it, parents believe and teachers believe it. The myth that math is a gift that some students have and some do not, is one of the most damaging ideas that pervades education in the US and that stands in the way of students’ math achievement.

Citizen Maths: A Free Course to Build Adult Math Skills

Do you want to improve your grasp of math so you can help your children understand their homework? Did math pass you by at school, or have your skills grown rusty over the years? Do you find it hard to apply what you know to the real-life problems you need to solve now—‌like using spreadsheets, interpreting data, or assessing risks?

If so, then the free, online, work-at-your-own-pace Citizen Maths course may be just what you need. Instead of abstract routines, the course uses practical problems to help you grasp some “powerful ideas” in math and see how these ideas apply in work and in life.

What Is Mathematics?

Here’s a bit of fun to brighten up your Monday:

What-Is-Math

  • Do you have a favorite place in the Land of Mathematics? Why do you like it?
  • Most children find themselves stuck in the inner city of Arithmetics. How can we help them get out and explore the landscape?

Pi: Who Needs That Many Digits?

From Numberphile: Pi is famously calculated to trillions of digits – but Dr. James Grime says 39 is enough.

How you round it off makes a difference:

An extra note from Dr. Grime: “Since pi39 ends in 0, you may think we could use pi38 instead, which has even fewer digits. Unfortunately, the rounding errors of pi38 are ten times larger than the rounding errors of pi39 — more than a hydrogen atom. So that extra decimal place makes a difference, even if it’s 0.”

Pi and Buffon’s Matches

From Numberphile: Dr Tony Padilla’s unique (and low budget) twist on the Buffon’s Needle experiment to learn the true value of Pi.

For a kid-friendly version of this experiment, try throwing food:

Pi Makes a River Bend

From Numberphile: “Sinuosity is a measure of how ‘bendy’ a river is. It is the length of the river divided by the direct route. Featuring Dr. James Grime.”

Update

After posting this video, Dr. Grimes and Lawrence Roberts began collecting and analyzing data about real-world rivers. It turns out the pi theory of sinuosity is too simple. Read about their results:
