Briefs we tested this kit with

1. "Why does the area of a circle equal pi r squared?" (20 s) Shots: the question `A = ?` writing on; a circle cut into 16 thin sectors that unroll into a near-rectangle (draw with canvas arcs, stagger the sectors); the rectangle's sides labelled `\frac{2πr}{2}` and `r`, then the line morphs `A = πr × r = πr^2` with a ring on the result.
2. "The derivative of x squared, seen as a slope" (15 s) Shots: `y = x^2` draws as a curve; a tangent (`plot.tangent`) rides along while a dot slides; a small slope readout counts up; the line morphs `\frac{dy}{dx} = 2x` with the `2x` in amber.
3. "The binomial square (a + b)^2" (12 s) Shots: `(a+b)^2` writes on; a square of side `a + b` splits into four coloured cells (use `cells()` as a model for a 2x2 build); the equation morphs into `a^2 + 2ab + b^2`, each term taking the colour of its cell.
