Mathlane

Mathlane turns three years of junior-high math into a path you can walk on your own. From positive and negative numbers in G7 to quadratic functions and circles in G9, 201 levels are ordered the way the ideas actually build — summer term first, then winter. Open the app and the next step is already there. ■ Three grades, one tap apart G7 — foundations: rational numbers, polynomials, equations, first geometry, inequalities, coordinates G8 — geometry and algebra step up: triangles, congruence, symmetry, factorising, algebraic fractions, surds, Pythagoras, parallelograms, first functions G9 — exam core: quadratic equations, quadratic functions, rotation, circles, similar triangles Progress is tracked per grade, so switching never disturbs what you have already done. ■ 68 hands-on labs, not another problem set The picture moves as you drag. Slide one triangle onto another to see what…
