Start the lesson - Maths
Rational and irrational numbers
Tell rational numbers from irrational ones, turn recurring decimals into fractions and find where √2 sits on the number line.
Start the lesson - Maths
Polynomials and factorisation
Learn degree and zeroes of a polynomial, use the identities for squares, and factorise quadratics by splitting the middle term.
Start the lesson - Maths
Linear equations in two variables
See why ax + by = c draws a straight line, and solve a pair of such equations by substitution, by elimination and by graphing.
Start the lesson - Maths
Quadratic equations
Solve ax² + bx + c = 0 by factorising and by the quadratic formula, and use the discriminant to predict how many real roots there are.
Start the lesson - Maths
Arithmetic progressions
Recognise a sequence with a constant difference, find any term with a + (n − 1)d and add up n terms with the sum formula.

How a lesson works
Read, try, practise, check
Every lesson follows the same four steps, so you always know what comes next. Parents and teachers can print the practice sheet and keep the answer key.
Read
A friendly explanation with worked examples and, in many lessons, a labelled diagram.
Try it at home
A small activity using things you already have. Some need a grown-up to help, and the lesson says so.
Practise
A practice sheet of 8 to 12 questions that prints on one or two pages.
Check
An answer key on its own page, so you can mark your own work and see where to look again.
