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 congruence means. Pull a parabola and watch the coefficient open and close it. Move a point around a circle and see why the inscribed angle is half the central one. You find the rule yourself instead of memorising it. ■ 126 lessons, explained one step at a time Every step is voiced, like a teacher sitting next to you. Then you answer out loud, and you get a response either way. ■ Practice that checks understanding Every unit has staged practice and a unit test. Wrong answers are explained on the spot, and you can
