Reflective symmetry is when a shape can be folded in half, with either side of the fold being a mirror image of the other. Rotational symmetry is when a shape can be rotated and it still looks the ...

When elementary students experience math through multiple modes, they begin to see it as a language of design, rhythm, and ...

On the road to algebra, children must learn a weird idea: that numbers can be smaller than zero (negative) and can be mixed with numbers greater than zero (positive) in an equation. Now researchers at ...

Symmetry is when one side of a shape is a mirror image of the other side. Lots of buildings and everyday objects use symmetry because it looks appealing to the human eye. But, if you step outside, ...

The equation in the title is the quintic equation, the mathematical genius is Évariste Galois (1811–32), and the language of symmetry he discovered is group theory. Symmetry combines both beauty and ...
