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
