Instructional Ideas

  • Introduce the lesson by giving each pupil a different number and ask them to find the first 10 multiples of their number; use the multiples later to find least common multiples of their numbers
  • Post the video as a homework reference

Classroom Considerations

  • Expects an understanding of using factor trees to find prime factors and representing the prime factorization using exponents
  • This video is hosted on YouTube

Pros

  • Shows multiple methods for finding the least common multiple

Cons

  • Does not provide an explanation of mathematics behind using factor trees to identify the least common multiple

Common Core
