Instructional Ideas

• Begin with a review of least common multiples and/or finding common denominators
• Create a set of practice problems of varying difficulty

Classroom Considerations

• Expects an understanding of multiples and distributive property

• This video is hosted on YouTube

Pros

• Demonstrates the process of finding the least common multiple in each of the three examples
• The use of color allows viewers to follow the steps more clearly

Cons

• Does not give an option for solving the equations using fractions throughout
