Teacher guide reSolve: Prime factorisation

TLF ID M021067

This sequence of four lessons explores prime factorisation. Students solve a puzzle using factor strings, play a dice game to learn about prime numbers, develop a method for finding all of the factors of a number, and engage in an investigation of highest common factors and lowest common multiples of two numbers, and how prime factors are related to this. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, a supporting PowerPoint presentation, discussion points and student resources. This sequence is part of the reSolve: Maths by Inquiry program.
