This PowerPoint, worksheet and answer key are perfect for teaching your KS3 students all about numbers and the number system. I have designed these resources to pair perfectly with the Kangaroo Maths system, but they will apply to other systems too. Key learning points covered include:

  • Find prime numbers and test numbers to see if they are prime
  • Find common factors of numbers
  • Find the highest common factor of numbers in simple cases, including co-prime examples
  • Find common multiples of numbers
  • Recognise and solve problems involving the lowest common multiple
  • Use linear (arithmetic) number patterns to solve problems
  • Recognise and use triangular numbers
  • Recognise and use square and cube numbers
  • Read, write and evaluate powers
  • Define and find square roots (including using the 鈭� symbol)
  • Define and find cube roots (including using the 鈭� symbol), including the use of a scientific calculator
  • Define and find other roots (including using the 鈭� symbol), including the use of a scientific calculator

This is a full lesson comprising beautiful slides, a worksheet and an answer key.
