208 Multifaceted Number Concepts
Successful Strategies
One of the most benefi cial ways to help students fi nd the
LCM is to have students show the multiples of each number
in a skip counting pattern. When students examine these
patterns it is easier to fi nd the common multiples and the
LCM. Students may show the multiples with numbers,
words, or models. The hundred chart serves as a valuable
tool in helping students to fi nd common and least common
multiples.least, common,
