Can anyone be a maths genius? – includes Marcus du Sautoy’s top tips.

“It’s absolutely critical. If children don’t crack fractions in primary school, they’ll never have a good grasp of algebra and ultimately will struggle with studying any STEM subject.”

Not sure that I get what this is all about, but interesting to discover it on the back of finding out about the simple english wikipedia. Where does the artistic element come into it?

This gives simple explanations for things like Pythagoras’ Theorem.

In mathematics, the

Pythagorean theoremorPythagoras’ theoremis a statement about the sides of a right triangle.One of the angles of a right triangle is always equal to 90 degrees. This angle is the right angle. The two sides next to the right angle are called the legs and the other side is called the hypotenuse. The hypotenuse is the side opposite to the right angle, and it is always the longest side.

The Pythagorean theorem says that the area of a square on the hypotenuse is equal to the sum of the areas of the squares on the legs. In the picture below, the area of the blue square added to the area of the red square makes the area of the purple square. It was named after the Greek mathematician Pythagoras:

If the lengths of the legs are

aandb, and the length of the hypotenuse isc, then, .

Has a website on Mindset:

In a fixed mindset, people believe their basic qualities, like their intelligence or talent, are simply fixed traits. They spend their time documenting their intelligence or talent instead of developing them. They also believe that talent alone creates success—without effort. They’re wrong.

In a growth mindset, people believe that their most basic abilities can be developed through dedication and hard work—brains and talent are just the starting point. This view creates a love of learning and a resilience that is essential for great accomplishment. Virtually all great people have had these qualities.

Teaching a growth mindset creates motivation and productivity in the worlds of business, education, and sports. It enhances relationships. When you read Mindset, you’ll see how.

This is the basic message that I want to get across to all my tutees. Maths can be tamed, and your understanding, and your grade, improved by the right effort.

Her section on Test your Mindset though is a bit disappointing, basically it is the same question asked 16 times. I tried it and came out with a fixed mindset, but I could just have easily responded in such a way as to be informed at the end of the “test” that I had an open mindset. The test is far too simplistic to be of any use.

Optimisation: some notes and commentary on how to approach these problems, at least as I see them.
