    GCSE video works backwards from a final result by identifying inverse operations and undoing a multi-step number process in reverse order.

  • Multiplication using the grid method

    Corbett Maths · Video · Opens on the provider website

    GCSE Foundation video partitions each factor by place value, fills every product cell in a multiplication grid and adds the partial products.

  • Sample space diagrams

    Corbett Maths · Video · Opens on the provider website

    GCSE probability video constructs two-event sample-space tables, lists every equally likely combined outcome and uses the completed grid to calculate probabilities.

  • Order of operations: BODMAS and BIDMAS

    Corbett Maths · Video · Opens on the provider website

    GCSE Foundation video applies brackets, orders or indices, division and multiplication, then addition and subtraction in priority order rather than simply working left to right.

  • KS3 Level Up: mental addition and subtraction strategies

    Pearson · Teaching · Opens on the provider website

    Pearson KS3 recovery guidance teaches partitioning the second number into tens and units, compensation by rounding then adjusting, and counting forwards to find a difference.

  • Calculating from related addition and subtraction facts
