Khan Academy offers free world-class lessons in maths from early years through GCSE, plus science, computing and more. Its strength is the hint system: stuck on a question and it shows the next step, not just the answer.
Learners earn points and badges for consistent practice, which keeps motivation up. Every topic has a short video explaining the idea before practice begins, so it works for learning something new as well as revising.
How families can use it: 15 minutes of Khan Academy practice a day builds real fluency in maths. Ask our Saturday tutors which topic to focus on - they can point you to the exact unit that matches your child's current classwork.
